Perfect Cube are those whose cube root is a positive whole number such as, 8, 27, 64, because 8 = 2×2×2, 27 = 3×3×3 and 64 = 4×4×4.
In order to find out whether the number is a perfect cube, you can check the cube root of that number. If the cube root is a positive whole number, then the number is a perfect cube.
The same definition can be used in case of a perfect square.
