3. A large aluminium sheet, coated black, is to be heat by inserting it in a heating chamber consisting two parallel plates. Plate A and plate B of the heating chamber are maintained at temperatures 500 K and 300 K, respectively. Both plates have an identical emissivity of 0.56. Assuming that area of each plate and the aluminium sheet are equal, determine the temperature of the aluminium sheet at steady state. (2 points)
