12. 1/20/2018 Situation: Mother is celebrating her birthday. Her children prepared a gift for her. They have a gift wrapping paper that measures 900 square inches. Each edge of the box is 12 inches. Do you think the children have enough wrapping paper to cover the gift? l

13. 1/20/2018 What kind of a plane figures of a face look like? How do we know if the wrapping paper is enough? What is the shape of the solid figure? How many faces does a cube have? How many edges does a cube have? How many vertices does a cube have?

14. 1/20/2018 Net Of The Cube.

15. 1/20/2018 Find the area of each face Area of a Square: = s X s = 12 X 12 = 144 square inches

16. 1/20/2018 Find the surface area of a cube The six faces of a cube are all square, then the surface area of a cube is 6 times the area of one face. In symbol. SA= 6 (side x side) or 6(s²) Where s is the side of a face which is a square

17. 1/20/2018 Surface Area of a Cube Formula: What is the total area of all faces = 6 ( s X s) Or 6 ( s ²) = 6 ( 12 cm X 12 cm) = 6 (144 cm ² ) = 864 cm ² Therefore, the children have enough wrapping paper to cover the gift.

18. 1/20/2018 Surface Area How do you call the total area of all faces of a solid figure?

19. 1/20/2018 Example 1 12 cm SA= 6 (s X s) = 6 (12 cm X 12 cm) = 6 (144 cm ² ) SA = 864 cm ²

20. 1/20/2018 Example 2 Find the surface area of a cube Whose edges is 8.3 cm? SA= 6 (s X s) = 6 (8.3 cm X 8.3 cm) = 6 (68.89 cm ² ) = 413.34 cm ²

21. 1/20/2018 Group Activity “Cube’s Figures Station” There are 3 stations inside the room. Each station has a given composite figure. The group will find the area of the figure. When the bell rings, the group is required to move to the next station. After completing the 3 stations, present your work by group & checking follows.

22. 1/20/2018 Group Activity

23. 1/20/2018 How do you work with your group? Did you help one another and share your ideas?

24. 1/20/2018 How will you able to find the surface area of a cube? The six faces of a cube are all square, then the surface area of a cube is 6 times the area of one face. In symbol. SA= 6 (side x side) or 6(s²) Where s is the side of a face which is a square

25. 1/20/2018 Find the surface area of the following cubes 1.1. 65 cm 2.2. 5.8 dm 3.3. 17cm

26. 1/20/2018 The learning targets of the day. I can visualize and describe surface area of a cube I can derives a formula for finding surface area of a cube I can solve surface area of a cube I can appreciate the value of sharing and helping one another
