Surface Area of Triangular Prisms

The video tutorial explains how to calculate the surface area of a triangular prism by breaking it down into its component shapes: two triangles and three rectangles. The instructor guides through the process of finding the area of each shape and adding them together to get the total surface area. The lesson includes a step-by-step calculation using given dimensions, resulting in a final surface area of 164 cm².
