In this problem you will estimate the heat lost by a typical house, assuming that the temperature inside is tin=20∘c and the temperature outside is tout=0∘c. the walls and uppermost ceiling of a typical house are supported by 2×6-inch wooden beams (kwood=0.12w/m/k) with fiberglass insulation (kins=0.04w/m/k) in between. the true depth of the beams is actually 558 inches, but we will take the thickness of the walls and ceiling to be lwall=18cm to allow for the interior and exterior covering. assume that the house is a cube of length l=9.0m on a side. assume that the roof has very high conductivity, so that the air in the attic is at the same temperature as the outside air. ignore heat loss through the ground.
