How to find the surface area of a triangular prism

The video tutorial explains how to calculate the lateral surface area of a prism. It begins by introducing the concept and then describes the characteristics of a prism, focusing on its base shape. The teacher uses drawings to simplify the understanding of the shapes involved. The lesson proceeds with detailed calculations of the areas of different sides of the prism, using the formula for the area of triangles and rectangles. The tutorial concludes with the final calculation of the total lateral surface area, emphasizing the importance of understanding dimensions and units.
