Calculating Surface Area of Rectangular Prisms

The video tutorial explains how to calculate the surface area of a rectangular prism. It begins with an introduction to the concept of surface area for three-dimensional figures, followed by a detailed explanation of the congruent faces of a rectangular prism. The tutorial then demonstrates how to calculate the surface area by finding the area of each face and summing them up. Finally, it introduces a formula for calculating the surface area of any rectangular prism, emphasizing the importance of understanding both the manual calculation and the formulaic approach.
