In the rhombus m< 1 = 160 what are m< 2 and m< 3

The others are either 160 and 70 or 70 and 70

The length of each side is 1ft. To calculate volume you have to do length x width x height=volume. If you are given volume, you switch the operation around. Each side of a cube is equal, so you know l,w, and h are all equal. So divide 3 by 3 and you get 1.
