This is an extension of section 11.2, "Surface Area of a Cylinder". Students developed formulas for finding the surface area of various platonic solids: cylinders, spheres, square-based pyramids, rectangular prisms and cones. After finding the surface area of these solids, we looked at 6 examples that would allow us to apply the formulas. All examples except for #5 have complete explanations (#5 just didn't have enough room).
