The total surface area is therefore six times the area of one face. The surface area of a cube is the total space occupied outside the surface of the cube. Since these are all the same you can multiply one of them by six so the surface area of a cube is 6 times one of the sides squared.
The surface area of the cube is 96 cm 2.
Each face has four edges and it makes a total of 12 edges in the cube. Use the Example sheet as a model to help you complete the Exercise sheet. The surface area of a cube is the total space occupied outside the surface of the cube. It is generally measured in terms of square units.
