Firstly, tanks rarely provide oxygen - they usually provide simple air or other breathable gas. Pure oxygen would kill you if you breathed it deeper than about 30 feet.
Second, the average Scuba tank holds the equivalent of about 80 cubic feet of gas under pressure. At the surface that would be enough to breathe off for about three hours for an everage person. But the deeper you go, the faster you consume gas because you breathe it under greater pressure.
