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