The student found the volume of the copper block by multiplying the area of its base by its height - Edexcel - GCSE Physics - Question 2 - 2016 - Paper 1

To measure the volume of the small stone, the student can use the water displacement method. Here are the steps:

1. Gather Materials: The student will need a graduated cylinder or a measuring jug filled with water, and the small stone.

2. Initial Water Level: First, the student should fill the graduated cylinder with a specific amount of water and note the initial water level.

3. Submerge the Stone: Next, the student should gently place the small stone into the water without spilling any water. It is important to ensure that the stone is completely submerged.

4. Measure the Displacement: The student should then observe the new water level in the graduated cylinder. The increase in water level indicates the volume of the small stone. The volume can be calculated by subtracting the initial water level from the new water level.

5. Record the Volume: Finally, the student should record the volume measured, which is equal to the volume of the small stone. This method works well for irregularly shaped objects, as it accounts for the volume displaced by the stone.
