Describe the process used to find the volume of an irregular solid such as a rock.

Immersing it in a liquid of known volume.

Explanation:

According to "The Archimedes principle" by completely immersing a solid in a liquid, the volume of liquid displaced will be equal to the volume of the solid.

We record the volume of the liquid before and after introducing the solid.

V solid = Vf-Vi

Vf: Final volume of the liquid

Vi=Initial volume of the liquid
