How long does it take to raise the temperature of the air in a good-sized living room?

A 1500-W heater is designed to be plugged into a 120-V outlet.

How long does it take to raise the temperature of the air in a good-sized living room (3.00 m times 5.00 m times 8.00m) by 10.0 degrees C? Note that the specific heat of air is 1006 (J)/(kg*degrees C) and the density of air is 1.20 kg/(m^3).

So far, I've figured out the following:

mass=144kg

W=1450kJ

I=12.5A

R=9.6-ohms
