Calculating Areas and Perimeters of Prisms

The video tutorial explains how to calculate the surface area of a right triangular prism. It begins by describing how two right triangles form a rectangle when combined. The area of these triangles is calculated using their base and height. The tutorial then covers finding the lateral area by using the perimeter of one triangle and multiplying it by the prism's height. Finally, it combines these areas to find the total surface area, expressed in square units.
