Area and Properties of Prisms

This tutorial explains how to calculate the surface area of a triangular prism. It breaks down the prism into three rectangular faces and two congruent triangular faces. The video demonstrates calculating the area of each rectangle and explains how to treat the triangular faces as a single parallelogram to find their combined area. Finally, it sums up the areas of all faces to determine the total surface area of the prism.
