What do you see in the picture?
A figure which is in
Okay, it is a figure that is in a rectangular rectangular shape.
shape.
Let’s see what happens in the figure. What
changes do you see? We formed it into a
solid figure; it has
grids or is divided
into cubes.
That’s right! It becomes a solid figure.
B. Establishing a Now we call this solid figure a prism. So what
Purpose for the is a prism?
Lesson
A prism is a solid figure with two
bases that are parallel and identical
polygons.
If the bases are rectangular in shape,
then it is called rectangular prism.
It has six faces, twelve edges and eight
vertices.
This 3-dimensional solid shape has six
faces that are rectangles.
The figure that you see in the picture is in
rectangular share, that’s why it is called a
rectangular prism.
This is the example of a rectangular prism.
This figure belongs to Ana.
Now, Ana has difficulty finding the volume of
this prism. Can you help Ana? What should you
do to help Ana finding the volume of the
rectangular prism?
C. Presenting How do you find the volume of a rectangular
Examples/Instance prism?
s of the New Lesson
There are three ways in which you can find the
volume of the rectangular prism.
FIRST:
Count the number of cubes to get the volume.
Let us count the cubes.
So, how many cubes are there in the prism? It has 24 cubes.
That is correct! The volume is 24 cubic units.
SECOND:
The rectangular prism presented contains of
cubes arranged in rows, columns and layers.
Can you identify the row part of the prism? The
columns? The layers?
How many rows of cubes are there? 3 cubes
How many columns of cubes are there? 4 cubes
How many layers of cubes are there? 2 layers
In the prism, there are 3 rows, 4 columns and 2
layers.
After identifying the number of rows, columns
and layers, you can now multiply the number of
rows by the number of columns and by the
number of layers.
Given Numbers:
rows:3
columns:4
layers:2
V= rows x columns x layers
V=3 X 4 X 2
V= 24 cubic units
THIRD:
There is another way to solve for the volume of
the rectangular prism. In the above example,
the column represents the length, the rows
represents the width and the layers represents
the height of the rectangular prism.
rows=width (w)
columns= length (l)
layers=height (h)
Or
Let V be the volume of a rectangular prism. If
the l is the length, w is the width, and h is the
height of the rectangular prism, then:
V= l x w x h
Solution:
Given: l= 3 cm, w=4 cm, h=2 cm
V= l x w x h
V=3 cm x 4 cm x 2 cm
V= 24 cu. Cm
If the given numbers are expressed in cm or m,
the unit of measure of the volume will be
expressed in cu. cm or cu. m.
Were we able to help Ana? Yes.
Example:
Find the volume of the rectangular prism:
Solution:
Given: l= 2 cm, w=5 cm, h=3 cm
V= l x w x h
V=2 cm x 5 cm x 3 cm
V= 30 cu. cm
Therefore, you can use the formula V= l x w x
h in finding the volume of the rectangular
prism.
