This document demonstrates how to calculate the total surface area of a rectangular prism with dimensions of 11cm by 8cm by 5cm. It works through calculating the area of each face (front, back, sides, top, bottom) and sums them to get the total surface area. The front and back areas are each 11cm x 8cm. The side areas are 2 x (8cm x 5cm). The top and bottom areas are each 11cm x 5cm. Adding all the face areas together using a calculator gives the total surface area of 366cm^2.
