Gold has a density of 19.3 g/cm^3. Current price is $1192 per troy ounce. What is the value of a cube of a gold with a side length of 1 inch? (1 troy ounce = 31.1g) (2.54cm=1inch)
Volume of cubic gold , V = side length 3
= (1 inch)3
= (2.54 cm )3
= 16.39 cm3
Density of gold , d = 19.3 g/cm3
So mass of gold , m = density x volume
= 19.3 x 16.39 g
= 316.3 g
= 316.3 / 31.1 troy ounce Since 1 troy ounce = 31.1g
= 10.17 troy ounce
Given the cost of one troy ounce gold is $1192
So the cost of 10.17 troy ounce gold is $1192 x 10.17 = $12122 .
