this is the full question: Accomplished silver workers in india can pound silver into incredibly thin sheets, as thin as 3.00x10^-7 m. Find the area of such a sheet that can be formed from 1.00 kg of silver.

So the density is 3.00x10^-7, and the mass is 1.00 kg right? how do i get the area??

Thousands of years ago, in Mayan civilization, the lead in thier pottery proves that the magnetic field was once reversed, meaning that the south pole was north, the north pole the south.
So, when this happens, the weather, the energies, everything is messed up as the force field of the earth begins to shut down in preparation to "flip". (Discover channel).
So, with this global warming, and the ice-caps melting, I was thinkig about the mythology stolen from the Mayan religion that originally speaks of the flooding of the earth...if the force field shuts down and completely melts all of the ice-caps, will this produce another flooding of our time?
