The reason I want to know this is because I just watched an episode of Alias, where she was buried alive, they managed to fly to cuba from the usa and dig her up....I know its just a TV show but I fort it was a bit far fetched, even if they knew where she was. I'm not a serial killer!

About 4 hours or so, maybe a little longer IF the person could stay calm enough to keep their breathing slow and not use up the oxygen too fast. Of course as the oxygen levels get lower, the heartrate would speed up in an effort to get more oxygen to the body, which would, in turn, speed up the brething causing the air to run out faster.
They actually did a test of such on the Discovery channel show Mythbusters a year or so back....and thats what the projection showed form the rate of oxygen usage during their tests....

When you're buried, the earth packs around the coffin therefore, cutting off the oxygen supply to the coffin.
Now how long a person can survive depends on the dimensions and thus the volume of the coffin since a bigger coffin would mean more air supply.
Also, you have to factor in heat. Because when you start feeling warm, you tend to breathe faster and more energy is used to cool your body.
Another would be if you panic and thus start hyperventilating. You'd be using up the air at a faster rate.
Generally though, only a handful of hours.

They did this on Mythbusters buried under soil, the coffin started to collapse before the air ran out, He lasted about 30 minutes and it was a steel coffin and it really scared him!
Unburied in a sealed coffin, he was pulled out after 50 minutes because of medical problems so maybe 60 minutes tops.
Yeh I'd say most films are far-fetched when they portray similar story lines!

Less time than you would think! It's no good measuring the volume of air used in a given time and extrapolating the results to match the volume in the coffin (minus the space taken by the body of the person). This wouldnt work because of the panic factor. The person would hyperventilate as panic set in thus not only breathing the air faster but suffering from the effects of excess CO2 well before the lack of oxygen killed them..

it is extremely a confusing question. Wadders tend to apply extra effective than folders. How huge is the family members you're thinking? A conservation tip for bathing room paper is to purchase Charmin extremely. that's thicker and extra absorbent than different manufacturers so which you employ much less. yet another is to count variety the sq. you're using. Charmin extremely works with some million-2 squares consistent with wipe.

I heard it is 3 hours in a coffin, 3 days without water & 3 weeks without food

Probably about maybe 2 hours 2 and a half hours.Around there. You would probably die from too much carbon dioxide that you are breathing out and that you don't have a lot of oygen when you breathe in again.

If you are put in a pine wood box, you would probably get a little more oxygen, as opposed to a steel casket. However, the dirt would seep in much faster.
