Surface Area of Pyramids pt 2
- mhargrove, Rasha Tarek
Big idea: figure out formulas for lateral and total surface areas of pyramids.
We're looking at a new three-dimensional shape. Some of the insights you've gained studying prisms will help you study pyramids. Play with the app a little before you answer the questions below. 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? B. How many bases are there? What shapes can they be? 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.) D. What needs to be added to the lateral area to find the total surface area?
