Determine the volume of the room in ft^3 and then convert that to liters.

OR, convert the dimensions of the room into cm, calculate the volume of the room in cm^3 and convert that to L by dividing by 1000.

Then, use the ideal gas law PV=nRT to calculate n. Finally, multiply n by Avogadro's number, and you've got the answer.
