The pyramids Have always fascinated at Cristina so she wants to build two model pyramids to put on her mantel. She wants here model of khufus pyramid to have a volume of 73.5 in.³ and a height of 4.5 inches what would the side length of the base of the pyramid be? Is this number a rational or in rational why

Part B
The volume of khafres pyramid is a bout 9/10 the volume of khufus pyramid. If Christina wants to make the second model pyramid so it’s volume is 9/10 The volume of the first model pyramid what value should she make the second model pyramid

Part C
If the height is 4.41 inches in the volume is the volume found in part B what will The side length of the pyramids base be? Is the number rational or inrational? why?

Part D
For the model to be to scale of the ratio of the Haight to the side length should be the same for both actual pyramid and the model. Is the model of khufus pyramid to scale? If not is it close?

Part E
