The total surface area of a solid can also be thought of as the area of the solid’s net. Examples: Given a bedroom in the shape of a rectangular prism, the total surface area is the area of the four walls plus the area of the ceiling and the floor. Given a cylindrical soup can, the total surface area is the area of the can’s label plus the
Surface area = sum of the areas of each surface of the solid In order to calculate surface area it is sometimes easier to draw all the surfaces Some sports relie on having very little friction. In biking for example, the smaller the surface area of the tires, the less friction there is. And thus the faster the rider can go.

(1) Measuring the surface (or boundary) constituting the solid. It is called the surface area of the solid figure. (2) Measuring the space region enclosed by the solid figure. It is called the volume of the solid figure. Thus, it can be said that the surface area is the measure of the solid figure itself, while
