As the others have mentioned it depends on location, site content (niche), number of ads, source of traffic and number of page views per visitor.
However, to give you a rough idea if we assume the following
All your visitors come from the US (CPC - $0.9)
They find your site via search engines
Each visitor views 3 pages on an average (so 6000 visitors have 18000 page views)
Your site is a general blog (no niche)
CTR - 1% (average)
then you should be able to make roughly $162 for 6000 visitors.
Regarding your second question, 60,000 visitors will simply make 10 times more.
can you tell what is right monetization method ?
sure i have done monetization of the video..jaroor bataonga when i make money...its old tarkhi videono one can give you exact figure or even a rough one.
because it all depends on what kind of visitors you are getting.
some poeple might make 1k$ with it
some might not even make a penny.
So if its a youtube video monetize it with adsense and you will find it out yourself,
and let us know how much you made
