Answer
Measurement of volume of an irregular solid Lighter than water by the displacement method
$a.$ Fill the graduated cylinder with water.
$b.$ Take a heavy solid $($eg. piece of metal$)$ insoluble in water. This metal piece is called the sinker.
$c.$ Tie the sinker to a strong string and lower it into the water gently and record the lower meniscus of water and let the value be $V_1.$
$d.$ Now take out the sinker and along with it tie the solid whose volume is to be measured and Iower them into the water.
$e.$ Note the reading carefully and Iet the value be $V_2f.$ The volume of the solid$, V = V_2 - V_1$
