Best ResponseYou've already chosen the best response.0first step is to build a cost equation: b*9+s*13=totalcost equation for base is length*width or b=lw sides = perimeter * height and perimeter can be found with (2l+2w) or 2lengths + 2 heights and l is equal to 2w so that can be subbed in where ever that appears b=2w*w or b=2w^2 sides = 2(2w) + 2w *h and the whole thing b*h=13m^3.......I think that is all the equations then find first and second derivative of total cost to find min cost
