Can someone help me with this with work shown thank you!

The interior of a refrigerator has a surface area of 5.6 m . It is insulated by a 2.2 cm thick material that has a thermal conductive ity of 0.0236 J/m . s . C. The ratio of the heat extracted from the interior to the work done by the motor is 7.9% of the theoretical maxi- mum. The temperature of the room is 29.1"C, and the temperature inside the refrigerator is 8.1"C. Determine the power required to run the compressor. Answer in units of W
