Part A-The pyramids have always fascinated Kristina, so she wants to build to model pyramids to put on her mantle. She wants her model of Khufuâs pyramid to have a volume of 73.5 inches and a height of 4.5 inches. What would the side length of the base of the pyramid be is this a rational or irrational? Why?
Part B- The volume of Khafreâs pyramid is about 9/10 the volume of Khufuâs pyramid. If Kristina wants to make the second model pyramid so itâs volume is 9/10 of 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 pyramids base be? Is the number rational or irrational? Why?
Part D- for the model to be 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 Khufuâs pyramid to scale? If not, is it close?
Part E- Is the model of Khafreâs pyramid to scale? If not, is it close?
