How could you explain the relative size of the great pyramid of Giza so that an American student might understand

The last remaining of the Seven Wonders of the ancient world, the great pyramids of Giza are perhaps the most famous and discussed structures in history. These massive monuments were unsurpassed in height for thousands of years after their construction and continue to amaze and enthrall us with their overwhelming mass and seemingly impossible perfection. Their exacting orientation and mind-boggling construction has elicited many theories about their origins, including unsupported suggestions that they had extra-terrestrial impetus. However, by examining the several hundred years prior to their emergence on the Giza plateau, it becomes clear that these incredible structures were the result of many experiments, some more successful than others, and represent an apogee in the development of the royal mortuary complex.

The three primary pyramids on the Giza plateau were built over the span of three generations by the rulers Khufu, Khafre, and Menkaure. Each pyramid was part of a royal mortuary complex that also included a temple at its base and a long stone causeway (some nearly 1 kilometer in length) leading east from the plateau to a valley temple on the edge of the floodplain.
