Solution
Volume of an irregular solid
- Take a measuring cylinder and fill water up to a certain level. Note down the level of water in the measuring cylinder. Let it be V1.
- Tie the irregular solid body with a thin and strong thread and lower the body gently so that the solid body is completely immersed in the water. The level of water rises. Solid-body displaces water of its own volume. Note down the new level of water. Let it be V2.
- Take the difference of two-level of water, i.e., (V2 – V1). This will give the volume of the irregular solid body.
