A cube of metal with density p kg 3288 m3 is at temperature 258°C. The cube is 0.155cm along each side, is made of a metal with heat capacity 251.7 and is in outer space. kgK If the cube emits as a blackbody, at what rate is the cube cooling at the instant described? Answer in degrees per second. The temperature in outer space is approximately 3K; neglect any incoming radiation.
