what is the maximum volume of an open top box that can be created with 300m sq of metal assuming none is wasted?
The Attempt at a Solution
so that means the surface area of the box must total 300 m sq
A(l,w,h)= lw + 2lh + 2wh = 300
and volume is given by
V(l,w,h) = lwh
my problem is when taking partials for l w and h in the area equation, I get 0 as the critical points. Are my equations wrong?
