The volume of a shape is the measure of how much three-dimensional space that shape takes up.
You can also think of the volume of a shape as how much water (or air, or sand, etc.) the shape could hold if it was filled completely. Common units of volume include cubic centimeters (cm
), and cubic feet (ft
This article will teach you how to calculate the volume of six different three-dimensional shapes that are commonly found on math tests, including cubes, spheres, and cones. You might notice that a lot of the volume formulas share similarities that can make them easier to remember. See if you can spot them along the way!
A cube is a three-dimensional shape that has six identical square faces.
In other words, it is a box shape with equal sides all around.
A 6-sided die is a good example of a cube you might find in your house. Sugar cubes, and children's letter blocks are also usually cubes.
Learn the formula for the volume of a cube.
Since all of the side lengths of a cube are the same, the formula for the volume of a cube is really easy. It is V = s
where V stands for volume, and s is the length of the sides of the cube.
A rectangular solid, also known as a rectangular prism, is a three-dimensional shape with six sides that are all rectangles.
In other words, a rectangular solid is simply a three-dimensional rectangle, or box shape.
A cube is really just a special rectangular solid in which the sides of all of the rectangles are equal.
Learn the formula for calculating the volume of a rectangular solid.
The formula for the volume of a rectangular solid is Volume = length * width * height, or V = lwh.
Find the length of the rectangular solid.
Learn to identify a cylinder.
A cylinder is a three-dimensional shape that has two identical flat ends that are circular in shape, and a single curved side that connects them.
A can is a good example of a cylinder, so is a AA or AAA battery.
Memorize the formula for the volume of a cylinder.
To calculate the volume of a cylinder, you must know its height and the radius of the circular base (the distance from the center of the circle to its edge) at the top and bottom. The formula is V = πr
h, where V is the Volume, r is the radius of the circular base, h is the height, and π is the constant pi.
Understand what a regular pyramid is.
A pyramid is a three-dimensional shape with a polygon for a base, and lateral faces that taper at an apex (the point of the pyramid).
A regular pyramid is a pyramid in which the base of the pyramid is a regular polygon, meaning that all of the sides of the polygon are equal in length, and all of the angles are equal in measure.
We most commonly imagine a pyramid as having a square base, and sides that taper up to a single point, but the base of a pyramid can actually have 5, 6, or even 100 sides!
A pyramid with a circular base is called a cone, which will be discussed in the next method.
Learn the formula for the volume of a regular pyramid.
Learn the properties of a cone.
A cone is a 3-dimesional solid that has a circular base and a single vertex (the point of the cone). Another way to think of this is that a cone is a special pyramid that has a circular base.
If the vertex of the cone is directly above the center of the circular base, the cone is called a "right cone". If it is not directly over the center, the cone is called an "oblique cone." Fortunately, the formula for calculating the area of a cone is the same whether it is right or oblique.
Know the formula for calculating the volume of a cone.
The formula is V = 1/3πr
h, where r is the radius of the circular base of the cone, h is the height of the cone, and π is the constant pi, which can be rounded to 3.14.
A sphere is a perfectly round three-dimensional object, in which every point on the surface is an equal distance from the center. In other words, a sphere is a ball-shaped object.
Learn the formula for the volume of a sphere.
The formula for the volume of a sphere is V = 4/3πr
(stated: "four-thirds times pi r-cubed") where r is the radius of the sphere, and π is the constant pi (3.14).
Find the radius of the sphere.
If the radius is given in the diagram, then finding r is simply a matter of locating it. If the diameter is given, you must divide this number by 2 to find the radius. For example, the radius of the sphere in the diagram is 3 inches.
Worksheet and Practice Problems to Calculate Volume
How do you find the volume of a box?
Math Instructor, City College of San Francisco
The volume of a box is equal to the product of the three dimensions of the box. You would multiply the length, the width, and the height of the box to find its volume. Make sure the dimensions have the same unit. Some tricky questions give different units for each dimension.

Here we will learn how to calculate the volume of three-dimensional shapes, including cubes, cuboids, prisms, cylinders, pyramids, cones and spheres. There are also volume worksheets based on Edexcel, AQA and OCR exam questions, along with further guidance on where to go next if you’re still stuck.
This free volume calculator computes the volumes of common shapes, including sphere, cone, cube, cylinder, capsule, cap, conical frustum, ellipsoid, and more.
Volume is the amount of space there is inside a shape. To calculate the volume of an object in three dimensions, we can use the various volume formulas. The formulae for the volume of a cone and the volume of a sphere are given to you for GCSE maths. You need to learn the other formulae. Volume is measured in cubic units. Metric units examples.
