It had 5 different shaped rectangle/squares that were easy to measure and kept all the ice shapes in one container. easy to fill and pop out like an ice cube tray. We had to modify the graph to accept surface are of a square. (we didnt re write the formula just used the surface area of a square calculator on a website of similar name and injected the end values into your graphing spreadsheet. Seemed to work. thanks.
