 Example: The total surface area of a cube is 4056 square metres. Find the length of its edge. Solution: Let the edge of the cube be l metres, Then we have the total surface area = 6l2 But we have given that the total surface area = 4056 square metres. \ 6l2 = 4056 Þ l2 = 4056/6 Þ l2 = 676 Taking square roots on both sides, we get Öl2 = Ö676 \ l = 26 \ The length of the edge of the cube = 26 metres.
