What is the difference between a cube and a perfect cube?

Answer 1

A cube is any number multiplied by itself three times, eg 2 cubed = 2³ = 2×2×2 = 8; 1.5³ = 1.5×1.5×1.5 = 3.375

A perfect cube is an integer (whole number) that is the cube of an integer, eg 8 is a perfect cube as it is 2 cubed, but 9 is not a perfect cube as 9 = 2.08008382...³

Answer 2

A "perfect cube" is the cube of an integer, usually of a positive integer - for example, the cube of 4 is 64, so that would be considered a perfect cube.A "cube" can be the cube of anything - thus, any real number is the cube of SOME number, called its cubic root.

Answer 3

A cube is a number of the form x*x*x where x is any numbers. For a perfect cube, x must be an integer.
