A piece of cardboard is being used to make a container that will have no lid. Four square cutouts of side length h will be cut from the corners of the cardboard. The container will have a square base of side s, height h, and a volume of 80 in³. Which is the correct order of steps for finding minimum surface area A of the container? s²h = 80 and A = s² + 4sh I. A'=2s - 320/s² II. 0=2s - 320/s² III. A = s² + 320/s² s = 5.429 in and h = 2.714 in I, III, II III, I, II III, II, I I, II, III
