# Prepare a Presentation

- Explain what you learned about surface area and volume of rectangular prisms. Use your work to support your explanations.

# Challenge Problem

Suppose that you made two other prisms, but this time you started with a half-sheet of paper like the one in the diagram. (The half-sheet measures 4$\frac{1}{4}$ by 11 inches.) Assume that these prisms have tops and bottoms.

- Compare the surface area of the prisms made with half-sheets to those made with whole sheets.
- How does the total surface area of each of these prisms compare to the whole-sheet prisms?
- Which set of prisms (the half-sheets or whole-sheets) has a greater difference in total surface area between the two types (short and tall) of prisms? Explain.
