Understanding Lateral Area of a Triangular Prism

The video tutorial explains how to calculate the lateral area of a triangular prism with base edges of 3 meters and a height of 5 meters. It begins by labeling the dimensions of the prism and then introduces the formula for lateral area, which is the perimeter of the base times the height of the prism. The tutorial visualizes the lateral area as a rectangle and demonstrates the calculation step-by-step, resulting in a lateral area of 45 square meters. The video concludes with a brief promotion of the math channel.
