1. The problem statement, all variables and given/known data There is a sheet of metal 30 x 12 inches long and you want to make a box by cutting x by x corners out at each corner of the sheet metal. (x will then be your height) The box will have no top to maximize volume. What is the maximum volume and what are the side lengths? 2. Relevant equations n/a 3. The attempt at a solution I don't really remember the question too much, but that is the image I drew associated with it. Basically, I am trying to find the maximum volume, and side lengths of the box. I made the equation f(x)=x(30-2x)(12-2x) Now, how do I find the maximum volume and side lengths?
