Gizmo Warm-Up

An object’s volume is the amount of space it takes up. The volume of an irregular object can be measured by how much water it displaces in a graduated cylinder. Place object 1 into the Graduated cylinder. (Notice the pin that holds the object in place so it doesn’t sink or float.)

What is the volume of object 1?

• 14.0 ml or cm^3

• 19 ml or cm^3

• 17.4 ml or cm^3

• 4.2 ml or cm^3
