A cube of gold 33 mm (about the size of an ice cube) long on each edge is worth about $23,300. If that is its value, how much is a gram of gold worth?

Answer 1

1 g = 1000 mm³

(33 mm)³ = 35937 mm³ * (1 g / 1000 mm³) = 35.94 g

35.94 g / $23,300 = 1 g / x

35.94x = 23,000

x = $648.48 per gram of gold in this case.
