Surface Area and Volume of Prisms

The video tutorial explains how to calculate the surface area of a triangular prism, which consists of two triangular bases and three rectangular faces. It covers the formulas for finding the area of triangles and rectangles, and provides example problems to illustrate the process. The tutorial emphasizes the importance of understanding the dimensions of each face and using the correct formulas to find the total surface area.
