Exploring Surface Area of Rectangular Prisms

The video tutorial covers the concept of surface area for rectangular prisms, explaining how to calculate it by considering the areas of all faces. It introduces the idea of a net, a 2D representation of a 3D shape, to simplify the calculation process. The tutorial includes examples to demonstrate the calculation of surface area using given dimensions, and encourages students to practice with exercises provided in the video.
