F. Pre-test
Direction: Tell whether the statement is true or false.
1. _______ Surface area is the sum of areas of all lateral faces and bases
of a solid figure.
2. _______ Net is a flat pattern that you can fold to form a solid figure
3. _______ Triangular has four rectangle lateral faces and two bases
4. _______ A cube has eight square faces and the total area of its eight square
faces are equal.
5._______ Pyramid has triangular lateral faces that meet on a common vertex
called apex.
B. TEACHING / MODELING
1. MOTIVATION (The teacher will show some objects.)
Imagine that you are invited to a birthday party. In the party there is a balloon,
party hut, banner, food and presents or gifts.
Since I mentioned the presents or gifts
-Do you receive a gift or a present on your birthday?
-What kind of present or gift did you received?
2. PRESENTATION
Directions: Read and understand the problem below.
Teacher Jocelyn celebrated her birthday last week. Her grade 6
Venus pupil’s surprised her with a rectangular mocha cake bought
in goldilocks. Now, I want to know the exact surface area of rectangular
mocha cake box?
3. DISCUSSION
1. Who celebrated her birthday last week?
2. What is the surprised of her pupils?
3. What solid figure is represented by the cake box?
4. How can we know the exact surface area of the rectangular mocha
cake box?
To know the exact area of the cake box we must find the surface area of the
rectangular prism represented by the box.
To determine the surface area of rectangular prism, you must identify what plane
figure is represented by every face of it. Let us know the surface area.
What is the surface area?
Surface area is the sum of areas of all lateral faces and bases of a solid figure.
Another way of describing the surface area of a solid figure is through
determining the area of its net.
What is the surface area?
A net is a flat pattern that you can fold to form a solid figure.
Look at the illustration below.
SURFACE AREA OF RECTANGULAR PRISM
The illustration shows that the surface area of the rectangular prism is the total
area of the six faces: the front, back, top, bottom, left and right.
The net of a rectangular prism consists of six rectangles. Both the bases and the
bases the lateral face of this shape is rectangular
Number of faces: 6
SURFACE AREA OF CUBE
A cube has six square faces. The total area of its six square faces is equal to its
surface area.
Number of faces: 6
SURFACE AREA OF TRIANGULAR PRISM
A triangular prism has three rectangular lateral faces and two bases which are
triangles. The sum of the areas of the bases and lateral faces is its surface area.
The triangles are the bases of the prism and rectangles are the lateral.
Number of faces: 5
SURFACE AREA OF PYRAMID
A pyramid has triangular lateral faces that meet on a common vertex called apex.
Its bases are a polygon. The sum of the area of the base and triangular lateral faces
is its surface area. The pyramid consists of four triangles. The base of the pyramid
is a triangle and the lateral faces are also triangle.
Number of faces: 4
C. GUIDED PRACTICE
4.Activities:
Directions: Visualize and describe the surface area of solid figures by completing
the table below, do it on your answer sheet.
