On a cold winter day, the outside temperature is –5.0 °C while the interior of a wellinsulated garage is maintained at 20.0 °C by an electric heater. Assume the walls have a total area of 75 m2, a thickness of 0.15 m, and a thermal conductivity of 0.042 W/(m • C°). What is the cost to heat the garage for six hours at these temperatures if the cost of electricity is $ 0.11/kWh? Note: 1 kWh = 3.6 × 106 J.
$ 0.61
$ 0.18
$ 0.44
$ 1.09
$ 0.35
