The product of the same three factors is called a **perfect cube.**

For example,

1 is a perfect cube because 1=1x1x1=1^{3}

8 is a perfect cube because 8=2x2x2=2^{3}

27 is a perfect cube because 27=3x3x3=3^{3}

64 is a perfect cube because 64=4x4x4=4^{3}

...

The **cube root** of a number is the opposite (or inverse) of cubing a number.

because 4x4x4=64

because 5x5x5=125

To find the cube root of a fraction, reduce the numerator and the denominator to perfect cubes is possible.
