Exploring Surface Area of Rectangular Prisms

This lesson covers how to calculate the surface area of rectangular prisms and cubes. It begins with an introduction to the concept of surface area, using real-life examples like cereal boxes and Rubik's Cubes. The lesson explains how to calculate surface area by finding the area of each face and adding them up. It includes detailed steps for using nets and identifying congruent rectangles. Example problems are solved to demonstrate the process, and the lesson concludes with a focus on calculating the surface area of cubes. Students are encouraged to practice with provided problems.
