Surface area is the measure of the total area that the surface of the object occupies (3D object). The surface area of a polyhedron is found by finding the sum of the area of all of the faces. The surface area is found between many three-dimensional (3D) shapes using formulas.
The surface area is useful because it tells us how much material is required in order to cover the object—for example, how much paint is needed to paint a table. Surface area is the sum of the faces, or surfaces, of a three dimensional shape.
