Volume .
Volume ( V ) is how much three-dimensional space a substance (solid, liquid, gas, or plasma) or shape
occupies or contains, often quantified numerically using the SI derived unit, the cubic meter. The volume of
a container is generally understood to be the capacity of the container, i. e. the amount of fluid (gas or liquid)
that the container could hold, rather than the amount of space the container itself displaces.
Three dimensional mathematical shapes are also assigned volumes. Volumes of some simple shapes,
such as regular, straight-edged, and circular shapes can be easily calculated using arithmetic formulas.
Units
Any unit of length gives a corresponding unit of volume, namely the volume of a cube whose side has the
given length. For example, a cubic centimeter (cm3) would be the volume of a cube whose sides are one
centimeter (1 cm) in length.
In the International System of Units (SI), the standard unit of volume is the
cubic meter (m3). The metric system also includes the liter (L) as a unit of volume,
where one liter is the volume of a 10-centimetre cube. Thus
1 liter = (10 cm)3 = 1000 cubic centimeters = 0,001 cubic meters,
So
1 cubic meter = 1000 liters.
Small amounts of liquid are often measured in milliliters, where
1 milliliter = 0,001 liters = 1 cubic centimeter.
Measuring Volume
The liter ( l ) is the unit of volume in the metric system. One liter is equal
to about one quart.
One liter contains 1000 milliliters (mI). One milliliter is 1/1 000 of a liter.
Graduated cylinders are used for measuring volumes of liquid.
They are made in many sizes. The level of a liquid in a graduated cylinder shows the volume of the
liquid. A milliliter is about the same volume as one cubic centimeter.
One milliliter of water has a mass of about one gram. Therefore, a liter of water is 1000 grams.
Volume formulas (V)
A measuring cup can be used to measure volumes of liquids. This cup
measures volume in units of cup and millilitres.
PROBLEM

of water will fill this dish?

Change:
25 cm3 = ………. m3
400 cm3 = ………. liter
44000cm3 = …….m3
55mm3 = ……. cm3
330000mm3 = ………m3
5 l = ………m3
35m3 = ………liter
20 m3 = ………liter
One cubic centimeter equals (1 ml, 1L, 1 kg, 1km).
There are (10, 100, 1000) milliliters in a liter.
The milli-means (10, 100, 1000, 1/1000).
