10. Water Displacement Method
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 (cm3).
*** Remember: 1 mL = 1 cm3 A B

11. A B Example #1 Volume of water in graduated cylinder A = 200 mL
Volume of water in graduated cylinder B =
270 mL
Difference in water:
270 mL mL = 70 mL
Volume of rock:
70 mL = 70 cm3 A B

15. 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
volume
solids are measured in cm3
V = L x W x H - regular-shaped solid
