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
