the ratio of the area of a face to the total surface area of cube is
Area of Cube = l2
Total surface area of Cube = 6l2
Ratio = Area of Cube / Total surface area of cube
Ratio = l2/6l2
Ratio = 1/6 = 1 : 6.
Total surface area of Cube = 6l2
Ratio = Area of Cube / Total surface area of cube
Ratio = l2/6l2
Ratio = 1/6 = 1 : 6.
