Math 9 Lesson #56 – Surface Area of Prisms/Pyramids Mrs. Goodman
Surface Area of Prisms • Formula: • S = Ph + 2B • P = perimeter • h = height • B = area of the base
Find the Surface Area • S = Ph + 2B
Find the Surface Area • S = Ph + 2B
Surface Area of Pyramids • Formula: • S = ½ PL + B • P = perimeter of base • L = slant height • B = area of the base
Find the Surface Area • S = ½ PL + B
Find the Surface Area S = ½ PL + B
That’s all for today! • Thanks for working hard! • See you next time!
