In this lesson I will teach you how to find the surface area of basic figures. Surface area has the same units of measure as area however the concept is a little different. One way to think of surface area is the amount of wrapping paper it would take to cover a box. Unlike basic area, surface area “covers” a basic figure in a 3 dimensional manner. As in other area topics we will be using formulas so take good notes and feel free to use a calculator. Also you should try to sketch the shapes of these figures when you practice as a drawing is always useful when modeling and solving a problem. Of course it’s not enough to just watch the lesson- you need to practice as much as you can as these basic geometry problems are everywhere in math and are common on exams like the SAT and GED.
