How can you determine the volume of an irregular solid (say a piece of brass)? Describe in steps with neat diagrams.

The volume of an irregular solid can be measured by using a measuring cylinder by the method of displacement of liquid.

1. Place a measuring cylinder on a flat horizontal surface.
2. Fill it partially with water.
3. Note the reading of water level very carefully. Let it be V₁.
4. Now tie the piece of brass with a thread and dip it completely into water.
5. The level of water rises. Note the reading of new water level V₂. The difference in the two levels of water gives the volume of the piece of brass.
