This document provides information about pyramids, including their parts and formulas for calculating their surface areas. It defines a pyramid as a polyhedron with a polygonal base and triangular sides meeting at a common vertex. The base is the bottom side and lateral faces are any non-base sides. Surface area of a pyramid can be calculated as the sum of the base area and total area of the lateral faces. The document provides examples of calculating surface areas for different types of pyramids and asks students to practice solving surface area problems. It concludes with assigning homework on calculating surface areas of pyramids and reading about surface areas of cones.

- 32. Question no.1 ? A tree-guard is constructed like a pentagonal pyramid. Find its surface area if the slant height is 10dm, base edge of 6dm, and an apothem of 3dm.
- 33. Question no.2 ? A tower is in the form of a pyramid whose base is a square of edge 18m and has a height of 120m. Find its lateral area.
- 34. Question no.3 ? The three pyramids of Giza were built as regular square pyramids. The pyramid in the middle is the Chephren¡¯s Pyramid and when it was built, its base edge was 707 ? feet, and a height of 471 feet. Find the surface area of Chephren¡¯s Pyramid, Including the base, when it was built.
- 35. PASS YOUR PAPERS
- 36. HOMEWORK ¨C USE YOUR MATH NOTEBOOK A. Solve: ? A tepee is constructed by using 12 poles. The construction leads to regular pyramid with a dodecagon for the base. With the base as shown, and knowing that the altitude of the tepee of 15 feet, find its surface area. (The length of the apothem is 7.5 feet.) B. Advance reading on surface area of cones. ? Guide Questions: ? What are the parts of a cone? ? How to solve for the surface area of a cone?
Editor's Notes
- Group into 3 Give pyramids
- Show the different pyramids and parts
- Also use the pyramids
- Now look at the activity sheets given. As you see, it has a pyramid with its dimensions. Applying the general formula, lets solve for the following.
- Don¡¯t let the students tell the answer, because they will still solve the others
- Don¡¯t let the students tell the answer, because they will still solve the others
- Don¡¯t let the students tell the answer, because they will still solve the others
- From what you have just done, let¡¯s now try to write the complete mathematical formula of each pyramid
- Solve the other two pyramids in the other groups 3 minutes each
- Next is presentation of answers
