question

A flat piece of plastic, area A = 1 ft^2 and thickness b = 0.252 inch, was tested and found to conduct heat at a rate of 3.0 watts in steady state with temperatures of T_0 = 24°C and T_1 = 26°C on the two main sides of the panel. Find the thermal conductivity of the plastic in cal sec^-1cm^-1 (°K)^-1 at 25°C.
