A 29.0 kg iron weightlifting plate has a volume of 3680 cm3. What is the density of the iron plate in g/cm3?

The density of a substance is given by dividing the mass by the volume.

The S. I units of density are kg/m³, but can be measured by other units such as g/cm³

The mass of the iron is 29 kg or 29000 g

Therefore; Density = 29000 g / 3680 cm³

= 7.880 g/cm³

Hence, the density of the iron plate is 7.880 g/cm³
