Question

The volume of a cube is 216cm3. What are the dimensions of the cube?

Answer 1

6 cm

Explanation:

The volume (V) of a cube = s³ ← s is the side length

Since V = 216 cm³, then

s³ = 216

Note that 6 × 6 × 6 = 216

Take the cube root of both sides

`\sqrt[3]{s^(3) }` =
`\sqrt[3]{216}`

s = 6

The cube has sides of length 6 cm
