Water Displacement Method
A B
Step 1: Add water to a graduated cylinder and record the amount.
Step 2: Place the object into the graduated cylinder.
Step 3: Record the volume of the water with the object.Step 4: Find the difference in water volume by subtracting.
Step 5: Convert the liquid volumemeasurement (mL) to the measurement for solid volume (cm3).*** Remember: 1 mL = 1 cm3
Volume of water in graduated cylinder A =
200 mL
Volume of water in graduated cylinder B =270 mL
A B
Difference in water: 270 mL - 200 mL = 70 mL
Volume of rock: 70 mL = 70 cm3

volume
volume – the amount of space an object takes up
liquids are measured in mL or l
graduated cylinders and beakers are used to measure liquids
solids are measured in cm3
V = L x W x H - regular-shaped solid
water displacement method - irregular-shaped solids
