The formula to use to find the surface area of cube is 6a 2 6a 2 6 a 2 6 5 2 6 25 150 The surface area of the cube is 150 cm 2 Example 2. What is the length of the edges of the cube if its volume is equal to 8 cm 3. Surface Area of a cube is the total area of the outside surfaces of the cube and is given by A 6a2 where a is the edge.
Or as a formula.
Since there are six sides the total surface area call it SA can be found as shown below. The total surface area is therefore six times the area of one face. V 54 cm 2. Let the length of the edges is a.
