Triangular Prism Surface Area and Properties

The video tutorial explains how to find the surface area of a triangular prism. It begins with an introduction to the prism's faces, identifying two triangular and three rectangular faces. The tutorial then demonstrates using the Pythagorean theorem to find the height of the triangles. With the height and base known, the areas of the triangles and rectangles are calculated. Finally, the surface area is determined by summing the areas of all faces.
