Heat Conduction of Wool Physics Question?

Your equation is right! Make sure that you converted all of your units correctly, all lengths need to be in meters and temperatures in Kelvin. Also, when you calculate the change in temperature use the skin temperature (in Kelvin) - the outside temperature. If you do all of this correctly then the units on your answer should only be Watts and you should get 300. Good luck on the exam tomorrow! :)
