What is the greater volume 1kg of copper or 1kg of gold?

The volume of a substance is determined by its density and mass. Copper has a density of 8.96 g/cm³ and gold has a density of 19.32 g/cm³. Therefore, 1kg of copper would have a greater volume than 1kg of gold because copper is less dense than gold. In other Words, the same mass of copper would take up more space than the same mass of gold due to their differing densities.
