Exploring Surface Area of Triangular Prisms

The video tutorial covers the surface area of triangular prisms. It begins with an introduction to the concept and proceeds with two examples: one for a regular triangular prism and another for a right triangular prism. The teacher explains the calculations step-by-step, encouraging students to practice on their own. The lesson concludes with a practice problem and a brief overview of the next steps.
