Elms Rectangular Prism Surface Area

1) What does surface area mean? 2) What does it mean to find the net of a prism? 3) Set a=5, g=4, c=3. What is the total surface area? 4) Set a= 6, g=2, c=2. Predict what is going to happen to the surface area. Will it be bigger or smaller? Now find the surface area. Was your prediction right? 5) Advanced: If I want to get a surface area to be 38 square units, what should the sides be?
