If you really want to learn about them....
The pyramid is estimated to have about 2 300 000 stone blocks weighing from 2-30 Tons each with some weighing as much as 70 tons.
There is so much stone mass in the pyramid that the interior temperature is constant and equals the average temperature of the Earth, 20 Degrees
Two types of limestone were used for construction. A soft limestone either pure or nummulitic was used for the bulk of the core blocks and a hard
white limestone for the mantle. Hard limestone becomes more polished with age.
The base of the pyramid covers 55 000m2 (592 000 ft2) with each side greater than 20 000m2 (218 000 ft2) in area.
The outer mantle was composed of 144 000 casing stones, all highly polished and flat to an accuracy of 1/100th of an inch, about 100 inches thick and
weighing about 15 tons each.
The average casing stone on the lowest level was 5 ft. long by 5 ft. high by 6 ft. deep and weighed 15 tons.
The mortar used is of an unknown origin. It has been analyzed and it's chemical composition is known but it can't be reproduced. It is stronger than
the stone and still holding up today.
The cornerstone foundations of the pyramid have ball and socket construction capable of dealing with heat expansion and Earthquakes.
There are no hieroglyphics or writing in the Great Pyramid.
With the mantle in place, the Great Pyramid could be seen from the mountains in Israel and probably the moon as well. It's polished surfaces would
have reflected light like a beacon.
Aligned True North: The Great Pyramid is the most accurately aligned structure in existence and faces true north with only 3/60th of a degree of
error. The position of the North Pole moves over time and the pyramid was exactly aligned at one time.
Centre of Land Mass: The Great Pyramid is located almost at the centre of the land mass of the Earth. At one stage in it's history it may certainly
have been. The east/west parallel that crosses the most land and the north/south meridian that crosses the most land intersect in two places on the
Earth, one in the ocean and the other at the Great Pyramid.
The relationship between Pi (π) and Phi (Φ) is expressed in the fundamental proportions of the Great Pyramid.
Numbers of relevance:
The length of a base is 9131 Pyramid Inches from corner to corner in a straight line.
The length of a base side at the base socket level is 9 131 Pyramid Inches or 365.24 Pyramid Cubits.
The length of a base side at sidereal socket level is 9 131.4 Pyramid Inches or 365.256 Pyramid Cubits.
The length of the perimeter at the sidereal socket level is 36 525.63629 Pyramid Inches.
The perfect formula height of the pyramid including the missing apex is 5 813.2355653763 Pyramid Inches, calculated from perimeter of base divided by
2 Pyramid Inches.
The height to the missing apex is 5 812.98 Pyramid Inches.
The volume of the pyramid is: V = 1/3 base area x height = 161559817000 cubic Pyramid Inches = 10339828.3 cubic Pyramid Cubits. [(5813.2355653 Pyramid
Inches)/3 * 9 131 Pyramid Inches * 9 131 Pyramid Inches]
