Answer: 22 ml
Explanation:
This is the Displacement method of finding the volume of an object.
It works by measuring the volume of water in a cylinder and then placing the object in the water. The new measurement is then taken and the previous measurement is deducted from it.
The difference is the volume of the object.
In this instance therefore, the volume of the object is:
= 52 - 30
= 22 ml
