A person's body is covered with 1.4 m2 of wool clothing. The thickness of the wool is 1.3 10-3 m. The temperature at the outside surface of the wool is 14°C, and the skin temperature is 36°C. How much heat per second does the person lose due to conduction?

You have a nice formula for this:

Heat transfer rate= K *area*deltaTemp/thickness You need to look up K, the heat conduction coefficent (joules/(C-m) ).
