Calculating Surface Area of Rectangular Prisms

The video tutorial explains how to find the surface area of a rectangular prism. It begins with an introduction and a British accent for fun. The concept of surface area is explained using a gift box analogy, followed by the introduction of the formula: 2 times the length times the width plus 2 times the length times the height plus 2 times the width times the height. The video then demonstrates how to apply this formula step-by-step, emphasizing the importance of the order of operations. The lesson concludes with a final calculation, resulting in a surface area of 34 centimeters squared.

What analogy is used to explain the concept of surface area?

• Covering a floor with tiles
