The result of multiplying a number, represented by the variable n, by itself twice is the number cubed. The given number is used in multiplication three times: n x n x n. It can be written as n with a superscript 3.
The cube of a number is also referred to as that number to the third power. The superscript 3, called the exponent, indicates the number of times the number has been multiplied (minus one). The term cubed is used since the formula for the volume of a geometric cube, with sides of equal length n, is n x n x n.
