A cube has a volume of 512 cubic inches. What is the length of one side of the cube?

A 8 inches
Since the shape is a cube, the length, height and width all have to have the same measure. If volume = l × w ×h and the volume is given as 512, then the cube root of 512 is 8 inches (8 ×8 ×8 = 512). The key is to find a factor which, when multiplied by itself 3 times, will yield 512.
B 128 inches
C 16 inches
D 64 inches
