The face of one side of a cube is a square shape. The formula for the area of a square
A=s² where s=side length
plug in the data we know
64cm²=s²
√64cm²=s
8cm=s
The side length on the cube is 8cm
The formula for the volume of a cube is
V=s³ where s=side length
plug in the data that we know
V=8³
V=512cm³
