Computing Surface Area of Triangular Prisms

The video tutorial explains how to compute the surface area of triangular prisms, focusing on a real-world problem where a tarp is needed to cover a tent. It discusses the components of a triangular prism, the problem context, and the calculation of the area of two rectangular faces. The solution involves determining the appropriate tarp size, emphasizing practical application of surface area concepts.
