588 Chapter 13 . Solid Shapes and Their 4. Recall that an n-gon is a polygon with n sides. For example, a polygon with 17 sides can be called a 17-gon. A triangle could be called a 3-gon. Find formulas (in terms of n) for the following, and explain why your formulas are valid: a. Number of faces (including the bases) on a prism that has n-gon bases b. Number of edges on a prism that has n-gon bases c. Number of vertices on a prism that has n-gon bases d. Number of faces (including the base) on a pyramid that has an n-gon base e. Number of edges on a pyramid that has an n-gon base f. Number of vertices on a pyramid that has an n-gon base 5. This problem goes with Class Activity 13C on the
