Suppose The Great Pyramid of Giza is the oldest and largest of the three pyramids in the Giza pyramid complex in Egypt. It is believed to have been built as a tomb for the Egyptian Pharaoh Khufu, over a 20-year period concluding around 2560 BC. The Great Pyramid is made up of an estimated 2.3 million blocks of limestone and granite, some of which weigh over 80 tons.
Can we infer that "The Great Pyramid of Giza was constructed in less than a year."? Yes, no, or maybe?
