Asked by Vix
There are about 200,000 glaciers in the world, covering 726,000 km2 with an average thickness of several hundred meters. In the process of global warming, the glaciers are slowly melting. Estimate the rise of the average sea levels in case they are all melted. Assume the radius of the Earth equals 6400 km.
pls help I got answer but for some reason its minus. Thx :)

yeah? How did you get a minus value?
Figure the volume of the glaciers.
The rise in sea level is that volume, divided by the surface area of the earth
Not strictly true, since not all of the surface is covered by oceans. But, as the sea level rises, the area of water increases, making it rise more slowly. Since they don't tell you the percentage of earth's surface that is covered by water, I guess you are to assume the whole area of the earth.

Yes, close enough, particularly considering the likely result.
