The US quarter has mass of 5.67g and is 1.55 mm thick.Convert the given thickness in mm to ft by using the following equivalent statement.1ft = 304.8 mmTherefore, the thickness of one US quarter is 5.09 * 10-3 ft.The number of US quarter in 575 ft is calculated as follows:575 ft *1 quarter/5.09*105 quarters= 1.13*105 quarters.

Answer:Therefore, the number of US quarters needed to have a stack of 575 ft is 1.13*105 quarters.

The stack weight of the US quarters can be calculated asThe number of US quarters is 1.13*105 quarters mul...
