Homework Statement
According to postal regulations, a carton is classified as "over-sized" if the sum of its height and girth (the perimeter of its base) exceeds 108 in. Find the dimensions of a carton with square base that is not oversized and has maximum volume.
Homework Equations
The Attempt at a Solution
I set up the equations.
h + 4x = 108
4x(h)=volume
h=108-4x
432x-16x^2=volume
432-32x=Dv/dx
432=32x
x=13.5
h=54
