One Cubic Unit
1 unit
(length)
1 unit
(height)
A unit might be
measured in
inches, feet,
centimeters, etc.
1 unit
(width)
How many cubic units is
this rectangle?
What did you
find?
Yes, it is 8
cubic units!
How about this one?
Remember…
there are some
cubes you can’t
see!
Watch...
Now Count Them
What did you
find?
Yes! There
are 12 cubic
units!
What’s the formula?
The formula for finding the volume
of a rectangle is ….
L x W x H = Volume
This means we take the length
times the width, then multiply
that by the height.
Let’s try it!
L=3
H=3
W=2
3 x 3 x 2 = 18
cubic units
Find the volume of this one!
What
did
you
find?
4 x 2 x 3 = 24 cubic units
