Yellow gold is an alloy that is 75.00% gold, 16.00% silver, and 9.00% copper (by mass). Calculate the cost of gold in a cube of the alloy 1.00 ft on a side. Use a weighted average of the densities of the elements for the density of the cube. The current price of gold (USD per troy ounce) is 1,969.95. The density of gold, silver, and copper is 19.3 g/mL, 10.49 g/ml, and 9.0 g/mL, respectively.
