A cup of coffee is enclosed on all sides in an insulated container 1/2 cm thick in the shape of a cube 10 cm on a side. The temperature of the coffee is 95C, and the temperature of the surroundings is 21C. Find the rate of heat loss (in J/s) due to conduction if the thermal conductivity of the cup is 2  10-4 cal/scmC.
