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.

mass=180kg and the volume=6m³.

then the formula to find density is= mass/volume

using this formula,180kg/6m³=30kg/m³

8 m³

Step-by-step 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

answer: 1, 3 and 5 are correct
