Part B The volume of Khafre’s pyramid is about 9/10 the volume of Khufu’s pyramid. If Kristina wants to make the second model pyramid so its volume is 9/10 the volume of the first model pyramid, what volume should she make the second model pyramid?

Part C

If the height is 4.41 inches and the volume is the volume found in Part B, what will the side length of the pyramid’s base be? Is the number rational or irrational? Why?

Part D
For the model to be to scale, the ratio of the height to the side length should be the same for both the actual pyramid and the model. Is the model of Khufu’s pyramid to scale? If not, is it close?

Part E
Is the model of Khafre’s pyramid to scale? If not, is it close?
