A large plywood box has a volume of 240 ft3. Its length is 16 ft greater than its height, and its width is 1 ft less than its height. What are the dimensions of the box?
------
Equations:
L = H+16
W = H-1
----
Volume = L*W*H = 240 ft^3
-------
(H+16)(H-1)(H) = 240
----
H^3 + 15H^2 - 16H - 240 = 0
------
H = 4 ft
L = H+16 = 20 ft
W = H-1 = 3 ft
----------
