There are THREE way to find volume in the chemistry classroom. You will need to know them in order to help you eventually determine the density of various objects.
REMEMBER:
Volume is the Amount of Space something takes up.

Method #1: With a Liquid Illustrate & Color this on your paper.
Meniscus
•The unit of measurement is usually in mL or L or cc

Cube and Rectangle Volumes are found by measuring their Length X Width X Height
BASE =
The unit of measurement is usually in mL or cm3……or any cubic unit
AREA
Method #2: With a Regular Shape Object

-cm3 = mL = cc
-A cube 1x1x1 cm can hold 1 mL of water.
cc stands for Cubic Centimeters
EQUIVALENT MEASUREMENTS

-Use DISPLACEMENT….the amount of water pushed out of the way by an object
-The unit of measurement is usually in mL or cm3 or cc
Method #3: With an Irregular Shaped Object
