Chandra wants to cover the entire face of the clock with a special gold foil.

She estimates that the angle formed by the hour hand and the minute hand of the clock is 60 degrees. She figures she will need 20 square inches of foil to cover the section bounded by those two hands. If Chandra's estimates are correct, how many square inches of foil will she need to cover the entire face of the clock?
