Exploring Surface Area of Rectangular Prisms

This video tutorial covers the concept of surface area for rectangular prisms. It explains how to calculate the surface area by unfolding the prism into a two-dimensional figure and finding the area of each face. The tutorial provides step-by-step instructions for calculating the surface area using both manual calculations and a formula. Several example problems are solved to demonstrate the process, emphasizing the importance of understanding congruent sides and using the correct dimensions.

What is the formula to calculate the surface area of a rectangular prism?

• SA = lw + lh + wh

• SA = l + w + h

• SA = 2lw + 2lh + 2wh

• SA = 2(l + w + h)
