The volume of water that would be displaced by a 2.5-kg cylinder of copper (the density of copper is 8900 kg/m³) is A) 2800 cm³. B) 280 cm³. C) 28 cm³. D) 2.8 cm³.

To find the volume of water displaced by the copper cylinder, we use the formula for density: Density = Mass/Volume. Rearranging this formula to solve for volume gives Volume = Mass/Density. Substituting the given values (mass = 2.5 kg, density = 8900 kg/m^3) and converting the volume to cm^3 (since 1 m^3 = 1,000,000 cm^3), we get Volume = (2.5 kg) / (8900 kg/m^3) = 0.0002809 m^3 = 280.9 cm^3, which rounds to 280 cm^3.
