Volume

The volume of an object is the amount of space it takes up. You will often measure the volume of liquids using a
graduated cylinder. ("Graduated" means that the cylinder is marked with measurement units.) Always read a
graduated cylinder at eye level. Also, water in a graduated cylinder has a curved surface called the meniscus. Read the volume at the bottom of the meniscus.

Hints: Always check the unnumbered marks on a graduated cylinder to see how many sections there are and what
they measure. Also, sometimes you have to estimate a measurement between two marks.

Prove to yourself that both graduated cylinders on the right contain 25 mL.

What is the volume of the liquid shown in graduated cylinders 1–4 below? What is the total volume in graduated
cylinder 5?

6. If the diagrams for Questions 4 and 5 show the same graduated cylinder before and after the rock was added, what
can you infer about the volume of the rock?
