How do you find the density of a coin?
Measure the diameter of one penny with a ruler, multiply by 1/2, square the result, multiply by pi to find the surface area, then multiply again by 5 centimeters to get the volume. Next, weigh the stack on an accurate scale. Divide the weight in grams by the volume to get the density.
What is the density of 4 quarters?
In 1965, the United States Mint removed all silver (density = 10.5 g/ml) from dimes and quarters. The new coins were made of a copper core (density = 8.9 g/ml) plated with nickel (density = 8.9 g/ml). In appearance, size, and volume, the coins remained identical to those minted before 1964 (see the 1932 quarter below).
