# What Does Volume Mean In Math

## Worked Examples: Calculating Volume

Volume: how to measure it | Measurement | Pre-Algebra | Khan Academy

Example 1

Calculate the volume of a cylinder with a length of 20cm, and whose circular end has a radius of 2.5cm.

First, work out the area of one of the circular ends of the cylinder.

The area of a circle is r2 . is approximately 3.14.

The area of an end is therefore:

3.14 x 2.5 x 2.5 = 19.63cm2

The volume is the area of an end multiplied by the length, and is therefore:

19.63cm2 x 20cm = 392.70cm3

Example 2

Which is bigger by volume, a sphere with radius 2cm or a pyramid with base 2.5cm square and height of 10cm?

First, work out the volume of the sphere.

The volume of a sphere is 4/3 × × radius3.

The volume of the sphere is therefore:

4 ÷ 3 x 3.14 × 2 × 2 × 2 = 33.51cm3

Then work out the volume of the pyramid.

The volume of a pyramid is 1/3 × area of base × height.

Area of base = length × breadth = 2.5cm × 2.5cm = 6.25cm2

Volume is therefore 1/3 x 6.25 × 10 = 20.83cm3

The sphere is therefore larger by volume than the pyramid.

## What Does Volume Mean In Shapes

Lesson Summary. Volume refers to the quantity of space that a 3-dimensional object occupies. Determining the volume of shapes can be done using certain formulas. The formulas for each of these shapes are: Cube volume equals s^3 where s is the side of the cube, V=s^3.

## What Is Volume Volume Definition

Volume is the amount of space that an object or substance occupies. Generally, the volume of a container is understood as its capacity not the amount of space the container itself displaces. Cubic meter is an SI unit for volume.

However, the term volume may also refer to many other things, such as

• the degree of loudness or the intensity of a sound
• the number or amount of something
• formal word for a book or one in a set of related books.

## What Are The Dimensions Of A Cube

A cube is a 3D object, so a cube has three dimensions:

• Length Generally understood to be the larger of the flat dimensions.
• Width Generally understood to be the shorter of the flat dimensions.
• Height or Depth The dimension that brings the shape into our 3D world

Notice, we have two ways to describe the third dimension:

• Height Use this term when the object rises before you, like a tall building.
• Depth Use this term if the object drops beneath you, like a hole in the ground.
• We need information about at least one of these three dimensions to measure the volume of a cube.

## Capacity In Relation To Volume

Capacity is the measure of the content of a vessel that holds liquids, grains, or other materials that take the shape of the container. Capacity is not necessarily the same as volume. It is always the interior volume of the vessel. Units of capacity include the liter, pint, and gallon, while the unit of volume is derived from a unit of length.

## How To Find Volume

The volume formula depends on the shape of the object. One of the most popular shapes is a rectangular prism, also known as a box, where you can simply multiply length times width times height to find its volume. Another common shape is a cylinder to find its volume, multiply the height of the cylinder by the area of its base . For other 3D shapes, check Omni’s Volume Calculator.

## Calculating The Volume Of Rectangular Boxes

Mathematics : What Is Volume in Math?
• 1Understand the volume of a rectangle equals it’s length x width x height. If your box is a rectangular prism or a cube, the only information you need is the box’s length, width, and height. You can then multiply them together to get volume. This formula is often abbreviated as V = l x w x h.XResearch source
• Sample Question: “If I have a box with a length of 10cm, width of 4cm, and height of 5cm, what is the volume of the box?”
• V = 10cm x 4cm x 5cm
• “Height” may be replaced with “depth.” For example, “The box has a length of 10cm, width of 4cm, and is 5cm deep.“XResearch source
• 2Measure the length of a box. If your are looking down at your box, the top appears to be a flat rectangle/The length the longest side of this rectangle. Write this number down as “length.”XResearch source
• Make sure you use the same measurement for each side — if you measure one side in inches, you need to measure them all in inches.
• 3Measure the width of the box next to the length. The width of the box is the other edge next to the length. If you are looking one side of the box, the width is the side the forms an “L” with the length. Write down this measurement as “width.”XResearch source
• The width is always the shorter side.
• 4Measure the height of the box. This is the last side you have not measured, and is the distance from the top of the box to the ground. Write this measurement down as “height.”XResearch source

Volume is a measure of how much space an object takes up. For example two shoe boxes together have twice the volume of a single box, because they take up twice the amount of space. … For example, in a cube we find the volume by multiplying the three side lengths together. In the cube above, the volume is 3×3×3 or 27.

## How Do I Use The Volume Calculator

Let’s look at the example of how to use this volume calculator:

• Select the 3D shape type. If you can’t find the shape you want to calculate the volume of, choose other special dedicated calculators . In this example, let’s assume you want to calculate the volume of a cylinder.

• Choose the right section of the volume calculator. In our case, it’s the part titled Cylinder volume.

• Type given data into proper boxes. Our cylinder has a radius of 1 ft and a height of 3 ft. You can change the units by a simple click on the unit name.

• Here you go! The volume of a chosen shape is displayed. In our case, it’s 9.42478 cu ft.

• If you want to check how much that is in US barrels unit, just click on the unit name and choose barrels from the drop-down list. Our cylinder has a capacity of ~2.24 oil barrels.

## How To Calculate Volume Volume Formulas

There is no simple answer to this question, as it depends on the shape of the object in question. Here are the formulas for some of the most common shapes:

• Cube = s³, where s is the length of the side.

• Sphere = r³, where r is the radius.

• Cylinder = r²h, where r is the radius and h is the height.

• Cone = r²h, where r is the radius and h is the height.

• Rectangular solid = lwh, where l is the length, w is the width and h is the height .

• Pyramid = Ah where A is a base area and h is the height. For a pyramid with a regular base, other equation may be used as well: Pyramid = * h * side_length² * cot, where n is a number of sides of the base for a regular polygon.

• Prism = Ah, where A is a base area and h is the height. For a right triangular prism, the equation can be easily derived, as well as for a right rectangular prism, which is apparently the same shape as a box.

## How To Find The Volume Of A Rectangle Vs Volume Of A Box

You can’t calculate a volume of a rectangle, a volume of a circle or a volume of a square because they are 2-dimensional geometric figures. As such, a rectangle does not have a volume . What you’re probably looking for is the volume of a rectangular cuboid , which is a 3-dimensional object.

To find the volume of a box, simply multiply length, width, and height and you’re good to go! For example, if a box is 5×7×2 cm, then the volume of a box is 70 cubic centimeters.For dimensions that are relatively small whole numbers, calculating volume by hand is easy. For larger or decimal valued numbers, the use of the volume calculator is very efficient.

## Calculating Different Shaped Boxes

• 1Find the volume of cylinders. Cylinders are tubes, where the top and bottom are circles. To find volume of a cylinder, use the equation V = pi x r2 x h. Where pi = 3.14, r is the radius of the top circle, and h is the height.XResearch source
• To find the volume of a cone, or pyramid with a circle for the bottom, use the same equation time 1/3. So, Volume of a Cone = 1/3
• 2Find the volume of a pyramid. Pyramids have one side, or base, and all of the other sides comes to a point. To find volume, multiply the area of the base by the height, and then multiply that by the fraction 1/3. Thus, Volume of a Pyramid = 1/3.XResearch source
• Most pyramids have square or rectangular bases. The area of a base is found by multiplying the length of the base by the width.
• 3Add the volume of the parts together to find the volume of complicated shapes. For example, if I need to find the volume of an “L” shaped box, there are more than three sides to measure. If you view the box as two smaller boxes, however, you can find the volume of each smaller box and add them together to get the final volume. With our “L” shaped box, for example, we can view the vertical line as a rectangular box and the bottom horizontal line as a square box.XResearch source
• Thought it becomes complicated, there are many ways to find the volume for any shape.
• ## Discovering Formulas For Volume

Students who understand volume as it is described above can reinvent for themselves many of the volume formulas that they are often asked merely to memorize. Each formula they derive helps strengthen their understanding for the other formulas they know. The volume of a solid all of whose faces are rectangles is found, as shown above, by multiplying the lengths of each of its dimensions: the product of its two base dimensions gives the area of the base, the height tells how many layers are in it, and the product of all three gives the volume.

When the faces of the figure are not all rectangles, we can sometimes dissect the figure and reassemble the pieces into a solid whose faces are all rectangles.

## Measuring Volume Of Liquids Solids And Gases

Because gases fill their containers, their volume is the same as the internal volume of the container. Liquids are commonly measured using containers, where the volume is marked or else is the internal shape of the container. Examples of instruments used to measure liquid volume include measuring cups, graduated cylinders, flasks, and beakers. There are formulas for calculating the volume of regular solid shapes. Another method of determining the volume of a solid is to measure how much liquid it displaces.

## Volume Of A Solid Formula

Here are the volume formulas for different regular solids:

• Rectangular prism

The volume of a rectangular prism is equal to the product of base area and the height of the prism:

Volume of a solid rectangular prism = l x w x h

Since we know all sides or edges of a cube are equal in length, then a cubes volume is equal to any side, or edge cubed.

Volume of a cube = a³

The volume of a prism is equal to the base areas product and the height of a prism.

Volume of a prism = Base area x height

= B x h

The volume of a cylinder is equal to the area of its circular base and a cylinders height.

Volume of a cylinder = r²h

The volume of a pyramid is equal to one -third the product of its base area and its height.

Volume of a pyramid = 1/3Bh

For a square pyramid, the volume is given as:

Volume =1/3s²h

Where s is the side length of the base and h is the height of the pyramid.

• Rectangular pyramid

The volume of a rectangular pyramid = 1/3 l w h

For a sphere, the volume is given as:

Volume of a sphere = 4/3 r³

Since a cone is a pyramid whose base is circular, therefore, the volume of a cone is:

Volume = 1/3 r²h
