You have a fixed volume. Need to find out what the max/min surface area would be. Volume is 1200. From my though process i think that this would be a integral problem based on lxwxh and 2wh + 2wl + 2hl relationship. Correct me if im wrong. Think of it as a gallons of air in a weather balloon with the surface area becoming flexible and mold-able. What would the external SA be if it would never be "measurable" in true l w h dimensioning. Lets say the material in the balloon is not elastic so there is no chance of deformation nor would the temp or density of the air change.
