Math Problem Statement
Sir Ched is planning to build a cold storage room. The inner layer will be made of cork board with the thickness of 20.5 mm, the middle layer of pine wood, and a concrete outer layer of 60.00 mm. If the inside temperature is -4 deg Fahrenheit, the outside temperature is 86 deg Fahrenheit and the area is approximately 40 m^2, respectively; compute for the thickness of the middle layer if the steady state heat transfer rate is 2050 BTU/hr.
