Question

The length of each edge of a cube is x centimeters. If x is in an integer, why can't the volume of the cube equal 20 cm3 ? Please help

Answer 1

see explanation

Explanation:

The volume (V) of a cube is calculated as

V = x³ ( x is the side length )

V ≠ 20

Since 20 is not a perfect cube

That is there is no integer when multiplied by itself 3 times gives 20
