The U.S. quarter has a mass of 5.67 g and is approximately 1.55 mm thick.

Part A

How many quarters would have to be stacked to reach 575 ft, the height of the Washington Monument?

Part B

How much would this stack weigh?

Part A. Convert ft to mm

575 ft = 575 x 304.8 = 175260 mm

Number of quarters to be stacked to reach 575 ft = 175260/1.55 = 113071 quarters

Part B. 1 quarter weighs = 5.67 g

So, 113071 quarters in this stack would weigh = 113071 x 5.67 = 641.11 kg
