This document discusses measuring and comparing volume and capacity using different metric units. It explains that measuring cups are used for dry goods and filled to the brim, while measuring flasks and cans are used for liquids and filled to the marked line. Capacity refers to how much an container can hold when full, while volume is how much is currently in the container. It provides examples of calculating capacity and choosing the appropriate unit for different materials, such as liters for water and gasoline or cubic meters for rock. The key relationship discussed is that 1,000 milliliters equals 1 liter and 1 milliliter equals 1 cubic centimeter.

1. Capacity and
Volume

2. Measuring Containers
Measuring cups -
For dry goods: Fill
to the brim.
Measuring
Flask – For
Liquid: Fill to
the mark.
Measuring can
– For gasoline:
Fill to the
mark.

3. Find the capacity
Pour The capacity is how much
something will hold
when it is full.
Full of water The volume is how much
there is.

4. Exercise:
1.The basin is filled to the brim with 3 liters
of water. What is the capacity of the
basin?__________________________________.
2.The milk in a carton is 300 milliliters
when it is full. What is the capacity of this
carton?_________________________________.
3.Eight 3 liter containers of juice will fill a
pail. What is the capacity of the
pail?____________________________________.

5. Cubic Centimeters and Cubic
Meters
1cm 1 meter
1cm
1cm
This metal box contains 1 meter
1 cubic centimeter 1 meter
of water The capacity of this tank is 1 cubic
meter. If the tank is full of water, then
the volume of water is one cubic meter.

6. Choosing the right unit
Example:
The syrup in the bottle is
750 cubic centimeters (cc).
Gasoline in the tank is 75
liters. Rock and stone for
mixing with cement is 2
cubic meters.
The larger
the thing you
measure, the
larger the
unit you use.

7. Exercise: Choose the correct unit to
measure the capacity of each of the items.
1. This month our family used 120 ______ of water.
a. cubic meters b. milliliters c. liters
2. My father fills the car with 40 ______ of gasoline before
leaving for Hua Hin.
a. milliliters b. cubic meters c. liters
3. Our father buys 6 ____ of sand to make our house fence.
a. Milliliters b. liters c. cubic meters
4. There are 10 ____ of wine left in the bottle.
a. Liters b. cubic meters c. milliliters

8. Comparing Volume
Metric system
1,000 milliliters = 1 liter
1 milliliter = 1 cc

9. Exercise: Find the answer.
1.How many milliliters are there in 2
liters? __________________
2.How many cubic centimeters are there in
3 liters? ___________________
3.How many milliliters are there in 8 cc?
___________________
4.How many liters are there in 4,000 cc of
oil?_______________
