It depends on how densely they're packed. But to get a first-hand estimate, do the following:

**1.** Determine the volume of a quarter. See information from the US mint.

**Diameter:** 24.26 mm; **Thickness:** 1.75 mm

To get the Volume, use this formula: **(pi) r2h**.

## V = (pi) r2h

## V = 3.14 x 12.332 x 1.75

## V = 835.4 mm³

**2.** Get the volume of 2L bottle in cubic millimeters:

## 2 L = 2000000 mm³

**3.** Now, divide the volume of the bottle by the volume of a single quarter.

Because of the irregularities of the shape of the container as well as the coin, the quarters only take about 75% of the total volume of the bottle (75% of 2000000 mm³ = 1500000 mm³).

## = 1500000 mm³ / 835.4 mm³

## = 1,796 quarters
