A square pyramid of height 7 inches has a volume of 60 cubic inches. If the volume of a similar square pyramid is 1620 cubic inches, what is its height? Answer 7 inches 10 inches 14 inches 21 inches
height is 21 inches 1620/60 = 27... cube root of 27 = 3..... the scaling factor on the height is 3 so it 7 x 3 = 21
