Researchers are conducting a study to quantity the thermal conductivity of a composite material. A square box is made from 1932 cm2 sheets of the composite insulating material that is 5.2 cm thick. A 125 W heater is placed inside the box. Sensors attached to the box show that the interior and exterior surfaces of one face have reached the constant temperatures of 71°C and 23°C. What is the thermal conductivity in W/m-K?
