Lets figure it out.
The ascending passage is approximately 1400 cubic feet.
The descending passage is about 6300 cubic feet.
The subterranean chamber is 16100 cubic feet (*)
Dead end pasasge is about 750 cubic feet (**)
Grand Gallery is about 15,000 cubic feet.
Kings Chamber is about 11,500 cubic feet
The Relieving chambers are 32,000 cubic feet (***)
Queens Chamber (passages) 2400 cubic feet (****)
Queens chamber: about 5000 cubic feet
Airshafts (x4): about 2700 cubic feet *****
Total: 93, 150 cubic feet. And for any odds and ends we might have missed, lets round up to
100,000 cubic feet for all interior passageways, chambers, airshafts, etc.
With the total volume of the Great Giza pyramid being 90,000,000 cubic feet that means that the interior chambers, passageways, airshafts, galleries, deadends, everything....
....accounted for 0.11% of the internal volume.
What granary in history allocated only 1/10th of 1% of its volume to storage?
* (
Measurements of the Great Pyramid puts the maximum height of the subterranean chamber at 3.94 meters or 13 feet.)
** using the width and height of other passages at 4' by 3.5'
*** Reveiling chambers above kings chamber are mostly filled with a series of nested stone rooves.
**** Using gizapyramid.com/measurements length of 125 feet with maximum height for full passage.
***** using longest length of 59 meters (194 ft), and dimensions of 0.7' x 0.7 feet. Four in total, northern and southern for king, another set for queen.
