The volume of a cube is found using the formula:



In this formula, a is the length of each side of the cube. The image below shows what we mean by the length of the side:

A Real Example of How to Find the Volume of a Cube

An Example Question

What is the volume of a cube with sides of length 6 cm, as shown below?

Step 1
Start with the formula:
Volume = a3
Don't forget: a3 = a × a × a (a cubed)

Step 2
Substitute the side length into the formula. In our example, a = 6.
Volume = 63 = 6 × 6 × 6 = 216 cm3
The volume of the cube with sides of length 6 cm is 216 cm3.
