Fill the cylinder about half way with water and measure the amount. Then drop the rock in and measure the amount of water. Now subtract no rock from rock in and that will give you the amount of volume displaced from the rock.
A graduated cylinder would be the appropriate lab equipment to find the volume of a small stone through water displacement method. Fill the graduated cylinder with water, measure the initial volume, add the stone and record the new volume to calculate the stone's volume.

A graduated cylinder may be used for small objects that are insoluble in a selected liquid. But that method would not work for determining the volume of a sugar cube (soluble in water) or a motor car (won't fit in a graduated cylinder!).
You can put liquids such as water, oil, or alcohol in a graduated cylinder for measuring volume accurately. It is not recommended to put solid objects in a graduated cylinder because it can affect the accuracy of the measurement.
Note the level of water in the graduated cylinder. Place the rock into the water carefully. Note the higher level to which the water rises. The difference between the old level and the new level is the volume displaced by the rock.
Volume displacement is the method used to find the volume of small or irregularly shaped objects by noting the difference in the level of liquid before and after after immersing an object into a graduated cylinder or beaker of liquid. For a small object immersed in a graduated cylinder or beaker, the volume displaced by the object can be read directly from the scale on the container.

A test tube is a cylindrical container used for holding small amounts of liquid or solids for testing or mixing. A graduated cylinder is a tall, narrow cylinder with volume markings used to measure the volume of liquids. The main difference is that a graduated cylinder is used for precise volume measurements, while a test tube is for general purposes.

You can use a graduated cylinder or a measuring cup filled with water to determine the combined volume of three small rocks. Simply measure the initial water level, then add the rocks and measure the new water level for the volume displaced, which represents the combined volume of the rocks.
If the object in question is water proof, and small enough. You can measure the amount of displaced water when it is placed in a tank full of water, this may not work for a lot of things but it can help when attempting to measure some objects.
