Measuring Volume using Water Displacement Method

What is the method used to find the volume of an irregular shaped object?

• water displacement

• density

• mass

• weight

To find out what the volume of the object is, we use the formula:

• New volume + old volume

• new volume - old volume

• old volume x new volume

• old volume = new volume

Let's practice! Before reads 50 mL. After we drop in the object, the new water level goes up to 60 mL. What is the volume of the blocks? (Hint: new volume- old volume)

• 8 cc

• 10 cc

• 60 cc

• 5 cc

What is the volume of the two red spheres? (Hint: new volume - old volume)

• 4 cc

• 6 cc

• 2 cc

• 8 cc

What is the volume of the ring? (new volume - old volume)

• 64 cc

• 68 cc

• 8 cc

• 4 cc

What is the volume of the cylinder?

• 10 cc

• 15 cc

• 8 cc

• 5 cc

What is the volume of the water in the empty graduated cylinder?

• 6 mL

• 32 mL

• 38 mL

• 48 mL

What is the volume of the graduated cylinder after the fish was placed in it?

• 32 mL

• 6 mL

• 48 mL

• 38 mL

What is the volume of the fish?

• 48 cc

• 38 cc

• 32 cc

• 6 cc

What is the volume of the water in the empty graduated cylinder?

• 4 mL

• 65 mL

• 69 mL

• 71 mL
