Question

A 75 gram bar of gold is cut into three equal pieces. How does the density of each piece compare to the density of the original bar?

1. Each piece is 1/3 the density of the original bar

2. Each piece is the same as the density of the original bar

Answer 1

You should know that density is the relation between, mass and volume as it is described in this equation: d = m/v. As the mass doesn't change in each piece, you will see that volume is less than the original, that's why each piece is 1/3 the density of the original bar or, you can also see, that you have increase by 3, the density original.
