A small building has a heater inside it running with its door left open. The heateris the only device in the building. When the heater runs, it consumes 250 W. The building is 3m X 3m X 2.5m. The temperature outside is 25 degrees celsius, and the the wind is blowing at 10km per hour. Estimate the temperature inside the building if the walls and ceiling are made of 13 mm thick plywood and 13 mm thick drywall with 100 mm of air inbetween. The floor is perfectly insulated and there aren't any cracks in the walls ceiling or door frame. Make any other reasonable assumptions as needed
