Question

is 1000 a perfect cube?

Answer 1

Think of a cube with side lengths of 10.

The volume of the cube will be L*W*H = 10*10*10 = 1000

This volume of 1000 is what we consider a perfect cube.

Answer: yes

Answer 2

10*10*10=$10^{3}$

10*10*10=1,000

1,000 is a perfect cube, because 10^3 is 1,000.

I hope this helps :)
