The average thermal conductivity of the walls (including windows) and roof of a house in the figure shown below is
$4.8 \times 10^{-4}$ kW/m $\cdot$ °C, and their average thickness is 23.0 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 24.1°C if the outside temperature is 0.0°C? Disregard surface air
layers, radiation, and energy loss by heat through the ground.
