The ratio of total surface area and volu...

The ratio of total surface area and volume of a sphere is 1 : 7. This sphere is melted to form small spheres of equal size. The radius of each small sphere is 1/6th the radius of the large sphere. What is the sum (in `cm^2`) of curved surface areas of all small spheres?
