Not really, considering you didn't know how many chapters were in a volume, alright then, if you've read the manga who is the true villian in FMA? Of course, you could just go to Wikipedia, but I want an honest answer.
EDIT:
45 pages on average x 10 = 450 pages a volume... wut?
There's four chapters average a volume, so uh... what?
EDIT:
You said assuming each volume has 10 chapters then you have read 6 volumes . But if a volume had 10 chapters it'd be the size of the bible, no joke:CitizenGeek said:Assuming each volume has 10 chapters, I would have read about 6 volumes in total. That is much more than enough to judge the entire series by.
