Question 301139
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
