The question simply asks (read slowly): What fraction of the earth’s volume is the molten part of the core?
I think I'm suppose to use the following equation since it has been stated in the book (though, I'm not entirely sure if I should):
surface area–to–volume ratio = (surface area)/(volume),
but that only includes the surface area, not the core which is what I'm looking for.
I also know that the Earth's density is 5.52 g/cm3, and we've also talked about the seismic waves in lectures (S- & P- waves) which might help me in figuring out the core's volume (or at least the molten part of it), which then I can use to compare to the Earth's volume (which I know is 1.08 x 1012 km3), although, these waves don't give me any numbers to work with. Can someone please help connect all those "clues" together?
