One way to mesure thermal conductivity is to mesure by putting the object in a closed box with known qualities. The heater maintains the same change in heat through the boxes wall.
We now that we have a total area of 2.16 m2 and thickness of wall of 3.90 cm. The heater is 60W and it maintains 40.0° change through the wall of the box. Find the thermal conductivity of the box.
