Final answer:
The logical problems with the Khufu pyramid were primarily related to its structural stability and alignment of the stones. Lack of hieroglyphics was more of a design choice than a logical problem.
Step-by-step explanation:
The logical problems with the Khufu pyramid primarily revolve around structural stability and alignment of the stones. The sheer size and weight of the stone blocks used in the pyramid posed challenges in ensuring that the structure would withstand the test of time. Additionally, achieving precise alignment of the stones was crucial to the pyramid's stability and aesthetic appeal. While lack of hieroglyphics may be considered a factor, it is not necessarily a logical problem but rather a design choice.
