  1. Apr 15, 2007 #1
    1. The problem statement, all variables and given/known data
    A box with a square base and open top must have a volume of 32,000cm^3. Find the demensions of the box that minimize the amont of material used.

    2. Relevant equations
    [tex]Sa(surface area)=4xy+x^2[/tex]

    3. The attempt at a solution
    I want to minimize Sa I am pretty sure so how do i begin?
