We're looking at a new three-dimensional shape. Some of the insights you've gained studying prisms will help you study pyramids.[br]Play with the app a little before you answer the questions below.[br]As a reminder, cutting out paper nets of pyramids will help you in your understanding.
A. What shape are the sides or "walls" of the pyramids?[br]B. How many bases are there? What shapes can they be?[br]C. Create a formula for finding the lateral area. (You'll need a variable that was in the previous exercise but not listed in this one.)[br]D. What needs to be added to the lateral area to find the total surface area?[br]
