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

To measure the volume of the small stone, the student can use the water displacement method:

1. Fill a Graduated Cylinder: Start by filling a graduated cylinder or overflow can with a known volume of water, making sure to record this initial volume accurately.

2. Submerge the Stone: Carefully submerge the small stone in the water, ensuring it is completely underwater. It is important that no water spills over the top of the cylinder before placing the stone in it.

3. Measure the New Water Level: After the stone is submerged, read the new water level on the graduated cylinder. The increase in water level represents the volume of the small stone.

4. Calculate the Volume: Subtract the initial water level from the new water level to find the volume of the stone. This volume can be expressed in cubic centimeters (cm³) or milliliters (mL), noting that 1 mL is equivalent to 1 cm³.
