A room of length 5m height 5m and width 5m is heated through the floor by maintaining it at a uniform temperature of 350 K. while side walls are well insulated. The heat loss takes place through the ceiling at 300K. Assuming that all surfaces have an emissivity of 0 8. determine the rate of heat loss by radiation through the ceiling.
