Cube root: 3
A perfect cube is a number that can be written as an integer multiplied by itself three times. It is the three-dimensional equivalent of a perfect square.
Example: 27 is a perfect cube because 3^3 = 27.
Can a perfect cube be negative?
Yes. Negative integers can also be perfect cubes.
Is zero a perfect cube?
Yes. Zero is a perfect cube because 0^3 = 0.
Does this accept decimals?
Yes. It checks any finite real value.
What if the root is not an integer?
Then the number is not a perfect cube.
