What volume of wood remains if a 2-cm hole is bored out of a cube with edge lengths of 4 cm?

1) Determine the volume of the cube. You are given the length of one side, which is all you need.

2) Determine the volume of the cylinder bored out. You know the diameter, from which you can get the radius; and you know the height is the same at the thickness of the cube.

3) Subtract the second volume from the first volume.
