The volume is irrelevant -- what is important is the force due to the mass in the black hole and the escape velocity. After a bit of algebra, you obtain the Schwarzschild radius, where R = 2 * G * Mass * c^-2. Therefore, a 10-solar-mass black hole has a radius 10 times greater than a 1-solar-mass black hole.
Thank you I see your point. But, hey would I have been right if we were talking about cheese balls? :-)
OBTW: You must be the reason I couldn't get the Freeper name I wanted back in 1998. Freegards.
