1. The foot-print of a US Bill (1, 5, 10, 20, etc) cubed is 0.06890922
2. Since there are 1,728 cubic inches in a 12 x 12 x 12 inch Cube
3. Divide 1,728 by 0.06890922 and get 25,076.4702
4. There is room for 25,076.4702 US Bills in one cubic foot
5. In a room 10 ft Wide & 10 ft Long & 8 ft to Ceiling
6. Multiply 25,076.4702 (1 cu ft) x 10 x 10 x 8 = 20,061,176.2 US Bills
One Bill is 6.6294 cm wide by 15.5956 cm long. One Bill is 0.010922 cm so the volume is 1.12921979833008 cubic centimeters 1 foot x 12 x 2.54 = 30.48 cm, so 1 cubic foot is 28316.846592 cubic centimeters If you can compress all the air out of the bills the 1 cubic foot would be 28316.846592 / 1.12921979833008 = 25076.470173367221396498175425582 round to 25,000 bills probably a lot less due to air separation of the bills.
