Surface Area of Rectangular Prisms

The video tutorial explains how to calculate the surface area of a right rectangular prism. It begins by introducing the concept and dimensions of the prism, followed by a detailed explanation of the surface area formula. The formula involves calculating the area of each face and summing them up. The tutorial then demonstrates the calculation using specific dimensions, resulting in a surface area of 432 square centimeters. The video concludes with a summary of the process.
