In this lesson, we learn how to find the surface area of a rectangular prism by calculating the area of each face and adding them together. The speaker emphasizes that rectangular prisms have symmetrical sides, so we only need to find the area of one side and multiply it by two. Using examples, the speaker shows us how to calculate the surface area step by step and reminds us to pay attention to detail when finding each side's area. By the end of the lesson, we are able to find the surface area of any rectangular prism.

I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
