The Great Pyramid of Giza was built using over 2 million hetrogeneous blocks of granite stone, each weighing as much as a car. Making the blocks hetrogeneous (meaning each block is of a slightly different shape and size) is incomprehensibly more difficult then making them homogenous (same shape and size). Not only are the blocks hetrogeneous but they are stacked to create an angle of 52 degrees. 45 degrees would have been much easier, but 52 degrees is necessary if you want your pyramid to include Pi and the golden ratio. Hetrogeneous blocks would be necessary to make your pyramid earthquake-proof.
