This is my first post on these forums, this problem is part of a lab and its part my end of year result but we never did anything on it in class so i have'nt a clue how to do it. Help would be really appreciated

The handle of a freezer door 12cm thick is attached by two brass bolts 0.75cm in diameter that pass through the entire door and are secured on the inside by nuts. The interior of the freezer is maintained at -32 degrees celsius and the room temperature is 34 degrees celsius; the thermal conductivity is 109W.M^{-1}.K^{-1}. Find the heat lost per hour through the bolts.

2. Relevant equations

Like i said, i haven't a clue. I dont know why we even were given this question.

3. The attempt at a solution
