V= s x s x s
V = 4 cm x 4 cm x 4cm
V= 16 cm x 4 cm
V= 64 cm
Very good! Explain your work.
(Pupil will explain his or her work.)
Very good!
4. Review
Class we’ve tackled yesterday about
volume of a cube. Who can give me
again the formula we can use to find the
volume of a cube.
V=sxsxs
Very good.
I have a cube here. It’s side is equal to
3 cm. What would be its volume?
Anyone of you who can solve for the
volume the given cube on the board?
Very good.
5. Motivation
Class, have you ever played a Jigsaw
puzzle?
Ok, I have 7 sets of jigsaw puzzle here.
Each group will be given one set of it.
Form the puzzle as fast as you can. The
fastest who can form the puzzle and
post it on the board is the winner of the
game. The winner will be receive an
additional 5 points in our activity later.
Setting of Standard
(Selected pupil will solve for the
volume of the given rectangular
prism.)
V=3cm x 3cm x 3 cm
V= 9 cm x 3 cm
V = 27 cm
Yes Sir!

3. (Remember that you should work as a
group or team. The noisy group/s will
be disqualified to our game)
A Rectangular Prism Sir!
(After 2 minutes declare the winner)
What kind of spatial figure you have
formed?
Very good. And that is our lesson for today:
SOLVING FOR THE VOLUME OF A
RECTANGULAR PRISM

dimensions.
Very good! And what are these

dimensions?
three dimension)
1. Length
2. Width
3. Height
Very good!
( Refer to the jigsaw Puzzle))
Anyone of you who can point out which

Puzzle)
Well done! Therefore class we have
identified the different dimensions of the
rectangular prism and these are the
length, width and the height. What do
you think now is the formula in getting
the volume of a Rectangular Prism?
V= L x W x H
Very good! I have here a Rectangular
Prism. Its length is equals to 7 cm, its
width is equals to 5 cm and its height is
equals to 3 cm. What would be its
volume? Let’s try to get the volume of
this rectangular prism using the formula
you had given and using the given value.
Ok, so what are the given values? Give
one
Very good! So we have now the
following given:
L= 7cm
W= 5cm
H= 3cm
L= 7cm
W=5cm
H= 3 cm

5. Let us now apply the formula you
identify a while ago. Again what is the
formula again?
Very good! And that is the first step
right?
Ok. After identifying the formula to use
in getting the volume of a Rectangular
Prism, what would be the next step?
Let us now substitute the given values
on the formula.
V=LxWxH
Very good! And after substituting the
given values, what would be the next
step?
Perform the indicated operation.
And what is the operation?
Multiplication Sir!
Very good! So 7cm x 5 cm is equal to?
35 cm
And 35 cm x 3 cm is equal to?
105 cm
Yes Sir!
Substitute the given values
V = 7 cm x 5 cm x 3 cm
Very good! Therefore the volume of this
rectangular prism is 105 cubic
centimeters.
Again what is the unit of measure used
in finding the volume of any spatial
figure?
In Cubic centimeters Sir!
Ok, do you want another example?
Yes Sir!
Ok, so suppose that the length of this
Rectangular Prism is 4 cm; the width is
5 cm; and the height is 3 cm, what
would be its Volume?
Again class what is the first step in
getting the volume of any spatial figure?
Identify the formula we are going
to use.
Very good!
And after that step what would be the
second step?
Substitute the given values!
Very good! And the third step is?
Perform the given or indicated
operation!

6. Multiplication Sir!
And what is the operation?
Box your final answer.
Very good! After performing the
indicated operation/s what would be the
last step?
Very good!
3cm
5 cm
4 cm
V=LxWxH
V = 4 cm x 5 cm x 3 cm
V = 20 cm x 3 cm
V = 60 cm
2. Enrichment Activity
Very good! Let us have another figure
2 cm
4 cm
8cm
( the second problem will solve by the
selected pupils in the board) (s/he
explain his answer )
V=LxWxH
V= 8 cm x 4 cm x 2 cm
V =32 cm x 2 cm
V = 64 cm
Well done! Let us give her/him 5 claps!
Did you understand our lesson for
today?
Are there still any questions regarding to
our topic for today which is the volume
of a rectangular prism?
Yes Sir!
None Sir!

7. 3. Generalization
What are the three dimensions of a
Rectangular prism?
Length
Width
Height
How do we get the Volume of a
Rectangular Prism?
By
using
V= L x W x H
Very good!
the
formula

8. 4. Application
Find the volume of the following rectangular prism. Fill in the box below the
corresponding letter of your correct answers to reveal the hidden word. Write your
complete solution on the Manila paper. Post your work on the board. The fastest group
who will post their work on the board and will complete the hidden word within the
allotted time will have the chance to explain their work on the front and will get
additional points in our group activity tomorrow.
Standards:
- You should work as a team.
- Show your complete Solution on the Manila paper and post it on the board.
- The noisy group/s will be disqualified to our game.
