Temperature Calculation For the Inside of Refrigerator/Freezer Combination Device
Assuming that the freezer is 20% and the refrigerator is 80% of the total volume.
Temperature inside the freezer = 1 F (degrees Fahrenheit)
Temperature inside the Refrigerator = 36 F
Therefore the average temperature inside the refrigerator/freezer is :
36 x 0.80 + 1 x .20 = 28.8 + .20 = 29 F
