A number’s cube root is a value that, when multiplied by itself three times, returns the original value. For example, the cube root of 27, denoted as 327, is 3, since we get 3 x 3 x 3 = 27 = 33 when we multiply 3 by itself three times. As a result, we can assume that the cube root returns a value that is essentially cubed. The sum of the cubes of the numbers 6 and 6 is 216. We lift the number x to the third power, or to the exponent 3, to find the cube of a number, x.
