Question

1. A cube has a volume of 125 cubic inches. What is the length
of each edge?

Answer 1

5 inches

Explanation:

Since the length of the sides of a cube are all equal,

volume of cube

= side ×side ×side

= (side)³

125= (length of side)³

Cube root both sides:

Length of each edge

`= \sqrt[3]{125}`

= 5 inches
