The sensor in your camera will ALWAYS take at the same dpi resolution and you can not change it, so if it is 300 dpi, that's what you will always get.
As far as the file size, this would vary as a function of your image quality. A 6 MP camera will produce files of varying sizes, depending on the complexity of the subject. It will not produce a 6 MB file shooting in jpeg. The highest file size you will commonly encounter is about 3 MB. If you reduce image quality by one factor, you will probably end up with 1.5 MB files. By "one factor," I mean, use "normal" instead of "fine;" "fine instead of "super-fine;" "3-star" instead of "4 star;" etc., depending on what your particular brand calls these things.

You can do the maths for yourself. 10" at 300 dots per inch is 3000 dots. 8" at 300 dpi is 2400 dots. One dot equals one pixel, so multiply the two together and you have 7 200 000 or 7.2 MP.
Oops you have a problem.
The file size of 1.5 MB at 6 MP sounds a little light to me. You can vary the amount of megabytes by varying the amount of jpeg compression. My 6MP DSLR gives jpeg images of around 3MB twice what yours is saying.

paper size = imagesize / 300 dpi
or
8x10 at 300 dpi mean you need at least 8*300 by 10*300 =>
2400x3000 pixels so your 6 Mpixels = OK.
