**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 = a

^{3}**Don't forget:**a

^{3}= a × a × a (a cubed)

Step 2

Substitute the side length into the formula. In our example, a = 6.
Volume = 6

The volume of the cube with sides of length 6 cm is 216 cm^{3}= 6 × 6 × 6 = 216 cm^{3}^{3}.
