Note: Round off your answer up to 3 decimal places.  Input only the numerical value. Researchers are conducting a study to quantity the thermal conductivity of a composite material. A square box is made from 838 cm2 sheets of the composite insulating material that is 2.8 cm thick. A 201 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 81°C and 38°C. What is the thermal conductivity in W/m-K?
