Calculating Surface Area of Rectangular Prisms

The video tutorial explains how to calculate the surface area of a rectangular prism by identifying congruent faces and calculating the area of each set of congruent rectangles. It covers the dimensions of the rectangles, the concept of congruency, and the final calculation of the total surface area, which is 62 square centimeters.

What does it mean when two shapes are congruent?

• They have the same color.

• They have the same size and shape.

• They are both rectangles.

• They have the same perimeter.
