Exploring Surface Area of Rectangular Prisms

This video tutorial explains how to calculate the surface area of a rectangular prism using its net. It begins with an introduction to the concept of surface area and the characteristics of a rectangular prism. The tutorial then demonstrates how to identify matching sides and calculate the area of each face using a net. Finally, it shows how to combine these areas to find the total surface area, emphasizing the importance of understanding units and squared measurements.
