Homework Statement
The airlines accept a box if length + width + height <= 62. If h is fixed, show that the maximum volume (62-w-h)wh is V = h(31 - h/2)^2.
The Attempt at a Solution
Well, I multipied:
V(h) = (62-w-h)wh
V(h) = 62wh - w^2h - wh^2
dv/dt = 62w - w^2 - 2w = 60w - w^2
0 = 60w - w^2
w = 60.
But this can not be. This is wrong. I tried other things but all of my attemps are wrong...
