The ones that I have seen at the Zoo were nothing close to 3metres long, maybe 1, or one and a half at the most.
That measurement is done with the tail and would perfectly fit a siberian tiger

. Siberian tigers "can" grow to enormous dimensions. For example - there are weight records of wild males that had more than 300 kg (A regular weight for siberians would still be around 200 kg).

How long do tigers usually live for?
In the wild not much longer than domestic cats. Between 15 and 18 years. In captivity it's usually between 20 and 25 - but with excellent treatment and occupation (such as in our park) it may be up to 30 years. However - that requires that the cat hasn't been tortured or mistreated too much, before she gets to us.

And how much space/room do they need?
Actually, in captivity we'll never be able to offer them the territories they deserve. In the wild they occupy territories of between 25 and 400 km2, always depending on where they live. Plus - unless they have young, wild tigers live a solitary life. Though - their behavioral pattern shifts when they're in captivity (as they don't need to hunt their food anymore) - they learn to like communities and to share their room with others, forming a social structure... which makes it possible keep them in the same habitat.
However - "space" is something that's always overrated by people... well, let's put it this way: the more room they have, the better it is. But what's essential in their life - that's occupation. In captivity they can't and don't need to hunt anymore - which results in boredom... and you can imagine that this can't really make them happy. Our practice is to occupy them, with 3 elements: "sports", changement of habitats and training for shows. The last one is only for those cats who like to do these shows... of course... it's a matter of talent, interest and not having fear from it - and no cats should be forced to do something they don't like.

I noticed that, about them being careful, but I also watched this TV show that showed a bunch of tiger attacks, I wouldn't blame them for attacking the people, though, they were pretty mean to them, and I'm sure a human wouldn't like it if they were hit with one of those whips multiple times.

I wouldnt.
Tigers never are "mean". They only make use of their weapons, if they're forced to defend themselves or to hunt for survival. But, what they're famous for, that's "Man-Eating". In connection to my studies on pantherines (which is why I'm finally working in the park now) I've written a nice article about that phenomenon:
