Question

An object has a mass of 7.2 kg and a density of 0.9 kg/m3.

Find the volume of the object in mº.

Answer 1

mass=180kg and the volume=6m³.

then the formula to find density is= mass/volume

using this formula,180kg/6m³=30kg/m³

Answer 2

8 m³

Explanation:

Let v represent the volume. Recall that density is mass/volume, which here is 0.9 kg/m³. To find the volume of this object, divide the density into the mass:

7.2 kg

--------------- = 8 m³

0.9 kg/m³
