TODAY’S AGENDA 10/9
UNIT 3: Metric System
FTF - Think – Pair – Share
(You and your buddy will each need 1 piece of paper for today’s FTF!)
Think: (Alone) Think about what volume is. Write down a definition or
draw a picture to explain it in your own words.
Pair: Talk with your buddy and together come up with an improved
definition.
Brain storm: On your table are several objects. Come up with a way
that you could measure the volume of these objects (draw a picture,
make a list, or write a few sentences).
Share what you came up with with the class!

With your buddy, please complete the following activity
and answer questions 1 – 4 (use 1 piece of paper)
Calculate the volume of one small cube.
Build an object that is 3 cm3 x 3 cm3 x 2 cm3. Describe
what you built on your paper.
Calculate the volume by applying the formula L x W x H.
What is your answer?
Count the number of cm3 cubes you used & write it down.
What relationship do you see between the number of cubes
you counted and the answer you got when you applied the
L x W x H formula?
Optional Challenge: Build an object with a volume of 24cm3.
Draw or describe what it looks like, how many cubes were
used, and what was the L, W & H.

THE SI UNIT KNOWN FOR
MEASURING SOLIDS WITH A

AS THE…

Cubic meter (m³).
THE FORMULA FOR CALCULATING
THE VOLUME OF A RECTANGULAR
OBJECT IS:
Volume = Length x Width x Height
THE SI UNIT KNOWN FOR
MEASURING SOLIDS WITH A
SMALLER VOLUME IS KNOWN AS
THE…

Cubic centimeter (cm³).
WHY IS THE UNIT CM³ USED
WHEN CALCULATING THE
VOLUME OF A RECTANGULAR
OBJECT?

When multiplying the object’s length, width and
height, the cm units are also multiplied
cm x cm x cm = cm³
GIVE IT A TRY!
SUPPOSE A CEREAL BOX IS 10 CENTIMETERS
LONG, 4 CENTIMETERS WIDE, AND 20
CENTIMETERS HIGH. WHAT WOULD BE THE
VOLUME OF THE BOX?
Volume = Length x Width x Height
Volume = 10 cm x 4 cm x 20 cm
Volume = 800 cm³

The SI unit used to measure solids with a larger
volume
A cubic meter is equal to the volume of a cube that
measures 1 meter on each side

HOW IS THE VOLUME OF AN
IRREGULAR SOLID SUCH AS A ROCK
MEASURED?


To measure the volume of an irregular solid,
immerse the object in water, and measure how
much the water level rises
This is called the water displacement method
HOW DOES THE WATER
DISPLACEMENT METHOD WORK?
 Record
the volume of water in the
graduated cylinder
 Carefully
place the irregular solid into the
water. Record the volume of the water plus
the object
 Subtract
the volume of the water alone
from the volume of the water plus the
object

Pick up one irregular shaped object. Record the name
in the data table.
Place some amount of water in the cylinder (at a level
higher than the size of the object).
Carefully read the meniscus and record volume to the
nearest mL on data table.
Slide the object carefully into the cylinder and record
the volume on data table.
Subtract the final volume from the initial value and
you will have the volume of the object. Record on data
table.
Pour water back into the beaker and retrieve the
object.
Repeat with remaining objects.
