A spaceship (consider it to be rectangular) is of size 5 x 8 x 7 (in meters). Its interior is maintained at a comfortable 20C, and its outer surface is at 119.3 K. The surface is aluminum. Calculate the rate of heat loss by radiation into space, if the temperature of outer space is 2.5 K. (This implies that the satellite is in the 'shade', i.e. not exposed to direct sunlight). Emissivity of AI-0.16. Stefan constant -5.669 x 10W/m2K
