## How to Find the Volume of a Cube

### Question

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

### Step-by-Step:

# 1

Start with the formula:

Volume = a^{3}

**Don't forget:** a^{3} = a × a × a (a cubed).

# 2

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

Volume = 6^{3} = 6 × 6 × 6 = 216 cm^{3}

### Answer:

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