Water Displacement Method AB 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 volume measurement (mL) to the measurement for solid volume (cm 3 ). *** Remember: 1 mL = 1 cm 3

Volume of water in graduated cylinder A = 200 mL Volume of water in graduated cylinder B =270 mL AB Difference in water:270 mL mL = 70 mL Volume of rock: 70 mL = 70 cm 3 Example #1
