**Reiny**, Friday, September 16, 2011 at 11:13pmlet each side of the squares cut out be x units

length of box = 41-2x

width of box = 28-2x

height of box = x

volume = x(41-2x)(28-2x)

expand and simplify, you will have a cubic

find the derivative, that will be a quadratic

set it equal to zero, and solve using the quadratic formula
