How much Volume is a TON(us) of air on a standered day at sea level? (standered day= 29.92psi at 70*F)?

Answer 1

You can figure this out yourself. From the first reference, the density of sea level air is about 1.2 kg/cubic meter. From the second reference, a US ton is about 907kg, so a ton of air is

907kg / (1.2kg/cubic meter) or about 756 cubic meters, or a cube just over 9 meters on a side.
