10. 9/17/2015Page 10 Practice - Volume and Surface Area volume What is the volume of this rectangular prism? B V = Bh l x w V = l x w x h ____ V = ____ What is the lateral area? surface area What is the surface area? ___________________ SA = ___________________

11. Cornell Notes Topic: Lateral and Surface Area; Volume EQ: How should I find the lateral and surface area of a 3-D shape?

12. Lateral Area (LA): the sum of the areas of the solid’s lateral surfaces P = PERIMETER of base (add all sides of the base) B = area of BASE (use different formulas according to the shape of the base) h = HEIGHT of the solid Total Surface Area (SA): the sum of the areas of all of its surfaces

13. Formulas for PRISMS LA = Ph Lateral Area = Perimeter of Base  height of prism SA = Ph + 2B Surface Area = Perimeter of Base  height of prism + 2  Area of Base

14. Station 1: Find the lateral area. (One base is the side that is on the ground.) 2.1 cm 3.6 cm 6.8 cm LA = ____ cm 2

15. Station 2: Find the surface area. 2.1 cm 3.6 cm 6.8 cm SA = _____ cm 2

16. Station 3: Find the lateral area. (One base is the side that is on the ground.) 6 m 8 m 9 m LA = ___ m 2

17. Station 4: Find the surface area. (One base is the side that is on the ground.) 6 m 8 m 9 m SA = ___ m 2

18. Formulas for Cylinders LA = 2  rh SA = 2  rh + 2  r 2

19. Station 5: Find the lateral area. Round to the nearest tenth. 5 cm 3.8 cm

20. Station 6: Find the surface area. Round to the nearest tenth. 5 cm 3.8 cm SA = 2  rh + 2  r 2

21. Surface Area of Pyramids and Cones Section 12.3 Goal – to find the surface area of a pyramid and the surface area of a cone

22. Pyramids are classified by the shapes of their bases

23. Surface Area verses Lateral Area of a Pyramid The lateral area of a pyramid: LA = P = Perimeter of the base l = slant height The surface area of a pyramid: SA = B = Area of the base

24. Example

25. Surface Area verses Lateral Area of a Cone The lateral area of a cone: LA = r = radius of the base l = slant height The surface area of a cone: SA =
