Question

Julie has a jewelry box shaped like a cube. If the volume is

216 cm³, what is the edge length of Julie's jewelry box?
A 14.7 cm
B 108 cm
C 6 cm
D 72 cm

Answer 1

Choice C: 6 cm

Explanation:

The sides of a cube are all of equal length

If each side is a cm, then the volume = a x a x a = a³ cubic cm

So a = ∛V where V is the volume

Since we are given V = 216 cm³,

each side = ∛21 = 6 cm

Answer 2

Answer: C) 6cm

Explanation:

6³= 6x6x6

6x6x6= 216
