Calculating Surface Area of Prisms

This video tutorial explains how to calculate the surface area of a prism by breaking it down into smaller parts. It covers calculating the areas of the top and bottom, front and back, and the sides of the prism. The tutorial then demonstrates how to sum these areas to find the total surface area, providing a step-by-step guide to ensure understanding.

What is the first step in finding the surface area of a prism?

• Find the area of the top and bottom

• Identify the shape of the prism

• Measure the height of the prism

• Calculate the volume
