Surface Area and Volume of Prisms

The video tutorial explains how to calculate the total surface area of a triangular prism. It begins by introducing the problem and the given dimensions of the prism. The instructor then details the process of calculating the surface area by dismantling the prism into its individual surfaces and calculating the area of each. The tutorial provides a step-by-step breakdown of the calculations, including the multiplication of dimensions and the use of formulas. Finally, the instructor concludes with the total surface area of the prism, ensuring the viewer understands the entire process.
