A cube has a side length of 8 inches.
Kazeer [188]

The answers are 8^{3} and 8 · 8 · 8

Explanation:

The volume of a cube or space a cube occupies is calculated by multiplying the length, height, and width. Additionally, because in a cube all sides are equal in length, the formula for volume is V= s^{3}. According to this, if the side length is 8 inches the volume can be represented as V = 8^{3} or V= 8 · 8 · 8 because the symbol · represents multiplication. Also, this can be solved as V = 512 cubic inches. This makes the following options correct:  8^{3} and 8 · 8 · 8.
