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.
