Answer 3

The perimeter of the face is the same as the perimeter of a square: you add up the lengths of each side. There are four equal sides that add up to 16. 4S=16 (as an equation) or if you like S+S+S+S=16
either way, S=4
the volume of a cube is \(S^3\) or S*S*S. So volume is 4*4*4= 16*4= 64 \( mm^3 \)
