Though I hate to do people's homework for them .. I'll help you out because the concepts here are hard to find reference for.
In medicine we most often quote the average human weight at 70 kg. From physiologic experiments done in the 1930's we can estimate that a resting 70 kg adult uses 3mL/kg/min of oxygen to maintain basic metabolism.
The room you have defined converts to ...
2.54 cm / inch, 12 inch / foot times ten foot ...
is 304.8 cm then cubed ...
28,316,846 cm cubed (or simply mL)
21% oxygen in the normal atmosphere so room size times 0.21...
5,946,537 mL pure oxygen in this room
5,946,537 mL oxygen with the average person consuming 3 mL/kg/min or 210 mL/min ...
the room has a surprising 28, 316 minutes of breathing time in it.
I was shocked by this answer but have run through it several times.
Addendum: I was thinking that the carbon dioxide being produced would probably overwhelm you long before this time.
