matt used centimeter cubes to make a solid that had a volume of 5 cubic centimeters and a surface area of 22 square centimeters. what might his solid looked like?
There are 6 cm^2 of surface for every cube. So if there are only 22 cm^2 for 5 cubes, there are 8 cm^2 of surface hidden between cubes, or 4 contacts between cubes.
So the 5 cubes can make up any shape as long as there are 4 contacts altogether, such as a rod, or a letter T, a letter L, etc.
