Cubes. The cube of a number is that number times itself times itself. 5 cubed, denoted 53, is equal to 5×5×5, or 125. 2 cubed is 23 = 2×2×2 = 8. The term "cube" can be remembered because there are three dimensions in a cube (height, width, and depth) and the number being cubedappears three times in the calculation. The square of a number is that number times itself. 5 squared, denoted 52, is equal to 5×5, or 25. 2 squared is 22 = 2×2 = 4. One way to remember the term "square" is that there are two dimensions in a square (height and width) and the number being squared appears twice in the calculation.
