VIDEO TRANSCRIPT

This is Giancoli Answers with Mr. Dychko. Density is mass divided by volume and we can solve for by multiplying both sides by V. So we get the mass of the air in the room is the density of air times the volume of the room. Air density is about 1.29 kilograms per cubic meter and the volume of the room will be its length times its width times its height so that's 5.6 times 3.6 times 2.4 meters and that gives about 62 kilograms total mass of the air.
