I have no clue who closed the original topic or why
romsek sent me a PM trying to help but the format he used didn't work in there so maybe it will work here.
You need to make a closed box with a square base and volume of 32,000 inches cubed . The material for the top and bottom of the box costs $1 per square inch, and the materials for the sides cost 0.25 dollars per square inch, Find the dimensions of the box that minimize the cost.
