This document discusses how to calculate the surface area of a rectangular prism. It explains that the surface area is the total area around the outside of the prism. To find it, you calculate the area of each face and add them together. The key steps are: 1) Identify the length, width, and height, 2) Calculate the area of the sides as length x height x 2, 3) Calculate the area of the faces as width x height x 2, 4) Calculate the area of the ends as length x width x 2, and 5) Add all the areas together. A formula is provided as surface area = 2 x (length x width + length x height + width x height). Examples are given
