Homework Help: chemistry/math

Posted by Hannah on Sunday, August 19, 2012 at 7:58pm.

The density of air at ordinary atmospheric pressure and 25C is 1.19 g/L. What is the mass, in kilograms, of the air in a room that measures 12.0 ft 12.5 ft 7.3 ft?

i made ft^3 into Liters and got 8,346,211.799 then I made the grams into kilograms and set up density = mass/volume and solved for x(mass) I got the answer to be 9.93e3. but that is wrong. what am i doing wrong? please help! thanks :)
