The average thermal conductivity of the walls (including windows) and roof of a house in the figure shown below is 4.8 x 104 kw/m - °C, and their average thickness is 20.8 cm. The house is heated with natural gas, with a heat of combustion (energy given off per cubic meter of gas burned) of 9,300 kcal/m3. How many cubic meters of gas must be burned each day to maintain an inside temperature of 27.3°C if the outside temperature is 0.0°C? Disregard surface air layers, radiation, and energy loss by heat through the ground. <137.0 5.00 m 8.00 m 10.0 m
