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

Cube Rectangle Prism

L x W x H L x W x H (½ L x W) x H

Method #2: With a Regular Shape Object

b x h a x h ½ b x h

-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

Initial Height of Water

350 mL

1st Water Level

Method #3: With an Irregular Shaped Object

Initial Height of Water

350 mL 350 mL

Place object into water and read level again.

1st Water Level 2nd Water Level

Method #3: With an Irregular Shaped Object

Initial Height of Water

350 mL

425 mL

Place object into water and read level again.

1st Water Level 2nd Water Level

Method #3: With an Irregular Shaped Object

Initial Height of Water

350 mL

425 mL

Place object into water and read level again.

1st Water Level 2nd Water Level

Method #3: With an Irregular Shaped Object
