The length of an airplane hangar is 20 ft less than 4 times its height h. The width of the hangar is 10 ft more than 2 times its height. What polynomial expression represents the volume of the hangar?
the height = h
length = 4h-20
width = 2h+10
Volume V = L * W * H
= (4h-20)(2h+10)h
=(8h^2+40h-40h-200)h
=8h^3-200h
