Basic science books may help here... about 70% of earth is filled with water. But, I guess the question is more geared towards your analytical skills...

For a back-of-the-napkin estimate, you could look up the surface area of the oceans, and multiply that by the average depth. That might be good enough.

None of the answers given here are particularly helpful...look up 'fermi estimation' -- that is what the interviewer is looking for with a question like this.
