Sorry I must have missed your answer.

Hum ok so 1 page = about 11.7 mb correct is that right pretty close always wondered : )

How did you end up in this result? I stated that one page is around 0.03424MB

...

Then we can calculate how much space does one page take:

10.272MB/300=0.03424MB

...

So in order to calculate how many pages are in 300MB ebook we simply divide one page size with that size:

300MB/0.03424MB = 8 761,68 = ~8 761 pages.

300MB can container 8761 pages

and one page takes 0.03424MB of space.

This isn't "exact" answer because there are other factors to consider such as metadata which can vary per page.
