A measuring cylinder is a tall, narrow container with graduated markings used in laboratories to accurately measure the volume of liquids. It is commonly made of glass or plastic and comes in various sizes.

- Fill the Cylinder: Pour water into the cylinder and record the initial volume (V1).
- Submerge the Stone: Carefully place the stone into the water so that it is completely submerged, making sure no water spills out.
- Record the New Level: Note the new water level (V2) once the stone is in the water.
- Calculate the Volume: Subtract the initial water volume from the new water level. The difference (V2 – V1) represents the volume of the stone.
