I need to know how much space 2,000 stars cover in our galaxy. I would do it myself, but I am not that good in mathematics so I ask for your help. In case you need to know the size of the stars and the density, i.e the distance between each star, use the average size and density of stars. The answer should be in percentage or a fraction form, that is the space that 2,000 stars cover to the total space our galaxy covers.Thank you.
P.S. It's not homework; I am not a student...

Use the average size and density of stars. The Galaxy's density is different, being higher towards its center and lower towards its edges. Find an average value for that and an average one for the size of the stars. I know what I am asking is difficult, but I really need to know the answer. Thank you.

I suppose our sun is an example of an average star. You can use its size... As you see I am not looking for an exact answer; rather an approximation.

It depends on the distance of the observer and the direction he/she is looking. There are star clusters that can have millions of stars in a small area, and there are areas where there are very few stars. The HST can observe a portion of the sky the size of 1/4 of a full moon (full moon as viewed from Earth) and see 100,000 stars or more.
UPDATE: The volume of the sun is about 1.41x10KM (1,300,000 Earth's), so 2000 stars of the same volume as the sun would have a volume of about 1.5548 x 10^34.

You know...this is a statistics question. You need to give more information...because, I could give you the answer of a square inch, and I would be right, because I could say the stars are just that small. Do you see what I'm saying?
