Calculating Surface Area of Prisms

The video tutorial explains how to find the surface area of a prism. It begins with an introduction to prisms and their properties, followed by an explanation of how to visualize a prism as a net. The tutorial then provides a detailed example using a shoebox to calculate surface area by summing the areas of each face. It generalizes this process into a formula for any prism, emphasizing the efficiency of using the formula over manual calculations. The video concludes by demonstrating the formula's application to quickly find the surface area.

What defines a prism in geometry?

• A solid with parallel and congruent polygonal bases
