Finding Surface Area of a Prism #kewl

The video tutorial explains how to calculate the total surface area of a three-dimensional figure. It begins by defining surface area and identifying the shapes involved, including triangles and rectangles. The instructor demonstrates how to calculate the dimensions of these shapes using basic geometry principles, such as the Pythagorean theorem for triangles. Finally, the video shows how to compute the surface area by adding the areas of all individual shapes.
