Question

The length of an airplane hanger is 20ft less than 4 times its height h. The width of the hanger is 10 ft more than 2 times its height. What polynomial expression represents the volume of the hanger?

Answer 1

Length=4h-20
Width=2h+10
Volume of hanger=L*W*H
h(4h-20)(2h+10)

Answer 2

(4h^2-20h)(2h+10)

Answer 3

8h^3+40h^2
-40h^2-30h

Answer 4

8h^3-30h=final answer I think
