Discuss how we measure the volume of an irregular body using Archimedes’ principle.
According to Archimedes principle, in order to measure the volume of a body, weigh it in air and in liquid.
W1 and W2 be the weight of body in air and liquid,
V be the volume of body, and
ρ be the density of liquid.
Now, as per Archimedes’s principle, decrease in weight of body in liquid is equal to the weight of liquid displaced by body.
