** To cube a number, we use the number in multiplication 3 times. A cube root goes the other direction. 3 cubed is 27, so the cube root of 27 is 3. The cube root of a number is the value that when cubed gives the original number. In arithmetic and algebra, the cube of a number n is its third power, the result of the number multiplied by itself twice:

**n ^{3} = n × n × n.**

n^{3} = n × n^{2}.
