Calculating Surface Area of Prisms and Pyramids

In this video tutorial, Jeff Jacobson explains how to find the surface area of prisms and pyramids. The process involves summing the areas of all the faces of the 3D shapes. The tutorial includes three examples: a rectangular prism, a triangular prism, and a square pyramid. Each example demonstrates how to use a net to unfold the 3D shape into a 2D representation, making it easier to calculate the surface area. The video emphasizes the importance of organization and labeling when working with nets.

What is the first step in finding the surface area of prisms and pyramids?

• Sum the areas of all the faces

• Calculate the perimeter of the base

• Add up the volumes of all faces

• Multiply the base area by the height
