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
Method #2: With a Regular Shape
Object
Cube and Rectangle Volumes are found
by measuring their Length X Width X
Height
BASE = AREA
The unit of measurement is usually
in mL or cm3……or any cubic
unit
Method #2: With a Regular Shape Object
Cube
LxWxH
bxh
Rectangle
LxWxH
axh
Prism
(½ L x W) x H
½bxh
Method #3: With an Irregular Shaped
Object
-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
