 Question 164842: As a homework problem, I am to construct a steel building 600 cu meters in size. My goal is to do it at the cheapest cost. Bldg: W X L X H = 600 cu meters Beams: \$20W + \$30L + \$50H = Total Cost I believe I have 4 unknowns, but I don't know how to set up the problem. Any help would be appreciated. THANK YOU!Answer by MRperkins(300)   (Show Source): You can put this solution on YOUR website!If you were just trying to make a cube, then the cheapest numbers would be W=600 L=1 and H=1 However this is not possible because you are trying to construct a steel building. You need to identify what the limits are that you can live with for the height and length and then make the rest of the measurment the width. A 1 meter tall building might be cheap but it would also be worthless. If you need additional help you can contact me at: justin.sheppard.tech@hotmail.com
