A body weighing 450 kilograms occupies a volume of 0.5 meters squared. Determine the density of the body.

m = 450 kg.

V = 0.5 m ^ 3.

ρ -?

The density of a substance ρ is the ratio of the mass of a substance m to the volume V that this substance occupies: ρ = m / V.

ρ = 450 kg / 0.5 m ^ 3 = 900 kg / m ^ 3.

Answer: the density of the substance from which the body is made is ρ = 900 kg / m ^ 3.
