Question

Which module represents that equation?

Answer 1

the one on the bottom left

Explanation:

Note that the cube on the bottom left is composed of

4 × 4 × 4 = 64 ← unit cubes

Thus the volume of the cube = 64 units³

The volume of a cube = s³ ← where s is the side length

Thus s³ = 64

To find s given the volume take the cube root of both sides, that is

s =
`\sqrt[3]{64}` = 4
