A cube number is a number that is the product of multiplying a number by itself and then by itself again. In other words, it is the result of raising a number to the power of 3). The symbol for cubed is 3, and it is written as a superscript next to the number, for example, 2³ = 8 or 3³ = 27). Cube numbers can also be represented visually as 3D cubes of single, unit cubes. The first ten cube numbers are 1, 8, 27, 64, 125, 216, 343, 512, 729, and 1,000. Cube numbers can be used to calculate the volume of a cube, which is a three-dimensional shape with sides of the same length, width, and height.
