A body weighing 210 g consists of a substance with a density of 7 g / cm. What is the volume of this body?

The formula for the density of a substance has the form: ρ = m / V, where ρ is the density of the substance that makes up the body, m is the mass of the body, V is the volume of the body.

Substituting the values we have in this formula, we get the following equation –

7 g / cm³ = 210 g / V. Hence – V = 210 g / (7 g / cm³), V = 30 cm³.

The required volume of our body will be equal to thirty cubic centimeters.
