Surface Area of Rectangular Prisms

The video tutorial explains how to find the surface area of a rectangular prism. It begins by describing the six faces of the prism and introduces the formula for calculating surface area. The tutorial then demonstrates the application of the formula with specific measurements, leading to the final calculation of the surface area. The importance of using squared units is emphasized, and the problem is concluded with the final result.
