WHAT IS VOLUME?
WHAT IS DENSITY?
November 15, 2013
Mass, color, shape, volume,
and density are some physical
properties of matter.
We understand mass.
We understand shape.
But what is volume?
What is density?
November 15, 2013
Density is an important physical property.
Density is the mass of a substance per unit volume.
Volume is the amount of space an object occupies.
November 15, 2013
In this investigation, we will try to
gain a better understanding of
volume and density.
November 15, 2013
We will start with volume.
Volume is the amount of space
an object occupies.
November 15, 2013
The volume of matter comes mostly
from the space between the particles.

Measuring the Volume of Solids
The method for determining the
volume of a solid depends on its
geometric shape. There are
formulas we can use to determine
the volume.

Today we are going to learn how to find the
volume of a rectangular solid object.
The formula for finding volume or
a rectangular prism is: l x w x h
(length x width x height)
November 15, 2013
Now you will practice
finding the volume of
some rectangular solids
using the formula of
l x w x h

Make sure this presentation is opened in
Notability.
Find the volume of the following solids.
Show your work on your iPad. When you
have finished finding the volume of all the
rectangular solids, raise your hand so your
teacher can check your work.

Density is found by dividing the mass
by the volume.
Density =
mass
