Answer:
The density of gold is 19.3 grams per cubic centimeter. 1 inch = 2.54 cm, so 1 cubic inch = (2.54 cm)3 = 16.387 cm3. Multiply volume x density: (19.3 g*cm-3)*(16.387 cm3) = 316.27 grams. Since 1 troy ounce = 31.1035 grams, (316.27 grams)(31.1035 grams/troy ounce) = 10.17 troy ounces {gold is usually priced in troy ounces} This is flawed mathematically gold does not have an Sg of 19.3 its really 12.7 grams per CC behind our heaviest natural periodic element mercury which is our heaviest element weighing 13.54 grams per CC so its really 12.7 x 16.387 =
208.11 grams of gold.
