oops, I didn't see the part about it being a solid. Well, I'm sure I saw it, but it didn't register. here's a trivia question for ya.
If one was to construct walls following the coastline of every land mass in the world, then gets some huge pumps and pump all the ocean water over these walls. How high would the walls have to be to contain all the water? Assume the water level is equal in all the "containers" Also pretend that all of the land has been rendered flat, no changes in elevation effecting the water displacement. Feel free to come up with your own explanations as to why and how this happened. I suppose this is really another math problem, but don't be afraid to treat like a trivia and guess away. The answer is in miles.
