A golden-colored cube is handed to you. The person wants you to buy it for $100, saying that is a gold nugget. You read that its density is 19.3 g/cm3. You measure the cube and find that it is 2 cm on each side, and weighs 40 g. What is its density? Is it gold? Should you buy it?

Density = 5 g/ cm3

Not Gold
