How much power does it require while operating

Solve the given question:

Question: A certain brand of freezer is advertised to use 880 kWh of energy per year.

Part A: Assuming the freezer operates for 6 hours each day, how much power does it require while operating?

Part B: If the freezer keeps its interior at a temperature of -6.0oC in a 20.0oC room, what is its theoretical maximum performance coefficient?

Part C: What is the theoretical maximum amount of ice this freezer could make in an hour, starting with water at 20.0oC?

Please clarify the equations and steps are used to get the answer. Thanks!
