A fireclay brick cube, 10 cm in length is removed from a furnace where it was maintained at a temperature of 500 degrees C. The brick cube is then placed in ambient temperature conditions. The heat flow from the brick is 400 Watts. The closest ambient temperature is:

a) 300 deg C.
b) 200 deg C.
c) 100 deg C.
d) 0 deg C.

By Stefan's Law, P = A * e * Stefan's constant * (T^4 - Tc^4)

P = 400 W, A = 6 * (length of ...
