Understanding Surface Area of Prisms and Pyramids

The video tutorial covers the concept of surface area for prisms and pyramids. It begins with an introduction to surface area as the sum of the areas of each face. The tutorial provides detailed calculations for the surface area of a rectangular prism, a triangular prism, and a pyramid, including a triangular pyramid. The instructor emphasizes the importance of listing or drawing each face and calculating their areas individually before summing them up. The video concludes with a reminder to show work and use a calculator if needed.
