The theory for this is called "Archimedes principle" and as the story goes that dear old Archie shouted "Eureka!", when he was taking a bath and figured it out.
He wrote this down as a law and it goes like this:

The formula for this is:
Apparentimmersedweight = weight - weight of the displaced liquid.
