Convert 12.0, 15.5, and 8.4 feet to cm.
Convert measurements to volume; i.e. length(cm) x width(cm) x height(cm) = volume in cc.
Change volume in cc to volume in L.
Then d = m*v. You have v and d, solve for m in grams and convert to kg.
Post your work if you get stuck.
The density of air at ordinary atmospheric pressure and 25°C is 1.19 g/L. What is the mass, in kilograms, of the air in a room that measures 12.0 multiplied by 15.5 multiplied by 8.4 ft?
