Given that the mean distance of the Sun from the Earth is 390 times bigger than the mean distance of the Moon from the Earth , evaluate the approximate ratio V(Sun)/V(Moon), V being abbr. for volume.

(In reply to solution and discussion by Charlie)

I agree.

One has to note, however,  that we were looking for an approximate ratio, calculated from not so accurate premises.
