Suppose you have Avogadro\'s number of mini marshmallows and use them to cover the state of Nebraska which has a land area of 7.687 × 104 mi2. Each mini marshmallow has a diameter of 0.635 cm and a height of 2.54 cm. Assuming the marshmallows are packed together so there is no space between them, to what height above the surface, in kilometers, will the mini marshmallows extend?
