How do you measure liquid volume using a Graduated Cylinder?

Practice

Another thing to consider when finding the volume of a liquid is the markings on the graduated cylinder. Look at graduated cylinder in the practice problem. The two lines that are marked are 6 mL and 8 mL. That means that each marking between 6 mL and 8 mL is equal to 0.2 mL. Graduated cylinders are often marked differently, so don't forget to check!

Multiple Choice

What is the volume of the water in this photo?

• 6mL

• 6.4mL

• 7mL

• 6.6mL

Take a look at the picture of the graduated cylinders on the left.

The cylinder starts with 200 cm³ of water.

When the rock is dropped in, the volume goes to approximately 270 cm³. (1mL=1cm3)

If you subtract 200 cm3 from 270 cm³ you get 70 cm³.

So the volume of the rock is 70 cm³.

Practice

Now you try to find the volume of a fish using water displacement.

Multiple Choice

• 40mL

• 6mL

• 38mL
