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

see explanation

Step-by-step 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

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
