•The amount of space
an object takes up or
occupies is called its
volume.
Milliliter = volume of a cube of
sugar
Cm

= 1mL
•1 mL = cm

•1000 mL = 1 L
•Volume is an
important property of
matter.
•We now know two
important general
properties of matter:
matter is anything
that has mass and
volume.
Determining Volume of a
Regularly Shaped Solid
•To determine the
volume of a regularly
shaped object (like a
cube or box), you
multiply the length by
the width by the
height.
•V=L x W x H
Determining the Volume of an
Irregularly Shaped Solid
•To determine the volume
of an irregularly shaped
object, we simply
submerge it into water.
•The volume of water that
the object displaces is
equal to the volume of
the object.
•This method is called the displacement method
and is credited to the Greek philosopher
Archimedes.
•He is said to have discovered the idea while taking
a bath.
•The farther down he lowered himself into his bath,
the higher he noticed the water rising.
•He hypothesized that the amount of water pushed
out of the way to make room for an object is the
same as the volume of the object.
