18. Example Problem Find the volume of the frustrum of a right pyramid with a square base, given the altitude of the frustrum, the length of a side of its upper base, and the length of a side of its lower base.

19. Step 1: Understand the problem What is given?  Altitude  Length of the upper base  Length of the lower base What is unknown?  Volume of the frustrum a b h a = lower base b = upper base h = height

20. Step 2: Devise a plan Is there a related problem?  The volume of a right pyramid can be obtained as follows: Can you restate the problem?  Find the volume of the large pyramid minus the volume of the small pyramid

21. Step 3: Carry out the plan  Calculate volume of large pyramid  Calculate volume of small pyramid  Subtract the second from the first

22. Step 4: Look back  This technique can be applied to other problems such as: Find the area of a donut, given the radius to the inside and outside.

23. Don’t be cryptic!
