            Surface Area of Pyramids - Lesson 12-2 
            Today, we looked at how to find the surface area of pyramids.  We started by defining this type of polyhedron: 
              
            After this, looked at finding the total surface area in the following two examples: 
              
            In order to find the total surface area, we looked at the base and the lateral faces: 
              
            We found their areas and added them to determine the total surface area of the pyramid: 
              
             
            We then looked at the following problem: 
              
            We found the total surface area as shown below:
