This is my theory of how the outer dimensions of the Great Pyramid's coffer were arrived at. It is all about certain square roots.

Firstly, I should state that the remen used in this theory is the Royal Cubit divided by sqrt 2, or 14.58 inches (rounded to two places), and the Royal Cubit length used is 20.62 inches, as established by Flinders Petrie. The dimensions used for the coffer were obtained from this page. They are within a small fraction of an inch of what I calculated myself from Petrie's measurements.

OUTER DIMENSIONS:
Height = 1048 mm = 41.26 in. = 3.4 ft
Width = 977 mm = 38.46 in. = 3.2 ft
Length = 2278 mm = 89.68 in. = 7.47 ft

The height appears to be simply 2 Royal Cubits, which at 20.62 inches would be 41.24 inches. This could also be viewed as one remen x sqrt 8

The width is one remen x sqrt 7, which would be 38.575 inches. Using Royal Cubits it would be x sqrt 3.5. Since that's not a whole number I have to assume that the remen was used for this dimension.

The length is one remen x sqrt 38 or one Royal Cubit x sqrt 19. Since 19 is a more practical number to deal with, I'm assuming that the cubit was used for this dimension. This would be 89.88 inches.

Why would the builders have an interest in the number 19? Hard to say but here are some possibilities;

Quote

The power of the number 19 and its proper use was a fundamental teaching in the Ancient Egyptian Temple Science. One of the primary grids used in Ancient Egypt to lay out designs on the Temple walls was the grid based on 19 vertical divisions; this is known to Egyptologists, but they have no idea of the significance of this fact. In brief, the number 19 is built into the spiritual blueprint of the human being and all of creation. It is related to an energetic grid surrounding every human being, which contains within it the precise positions and functions for all of the spiritual energy centers in the human being (not only chakras, but a large number of power centers not taught publicly by any tradition even today.)

The Egyptian priesthood knew that the Grid of 19 was in reality the background of the human archetypal energy blueprint. They also knew that the correct use of the 19 in design (as 19 design elements, or by building the number into measurement and proportional systems in design) creates a very powerful emanation of beneficial energy; this is the Golden Light often referenced in ancient Egyptian texts as essential for spiritual development and for consciousness after death.

So I suspect that it was intended to confer some sort of beneficial effects on the coffer.

I don't think they had an interest in any particular number.  I do, however, think it was the right size to accommodate the wooden sarcophagus -- and that this object was to a specific dimension because of the size of the king and number of interior coffins.

Had it been to some specific number, we would see this repeated in other sarcophagi AND there would have been some references in the texts about these numbers.

Not necessarily. Maybe the GP was a special case. Do the other pyramids have a Grand Gallery and two chambers up above ground level? There is nothing typical about the GP. Do you seriously expect me to believe that all three coffer dimensions can be obtained  to within a fraction of an inch through multiplying remens or cubits by square roots through simple chance? Is the coffer's height 2 cubits by simple chance? Then why should the other two dimensions be? The only other explanation put forward, like yours for instance, is just arbitrary sizing to the general shape of a human body and coffin. I don't find that at all convincing, sorry. I haven't checked the dimensions of Khafre's and Menkaure's coffers. Maybe they also have mathematical/geometrical relationships.

I just checked the Khafre coffer dimensions and they are length 5 cubits, height one remen x sqrt 7 and width 2 cubits. So the height and width are the same as the GP coffer but switched around. The length is simpler than the GP coffer, an even 5 cubits. But then why is the GP coffer length not 5 cubits also? The khafre coffer dimensions can be found here. Petrie doesn't provide the dimensions of Menkaure's coffer and it is lost. I guess that's the one that sunk with the ship that was carrying it to Britain.

When you get to mess around with various square roots, why, yes, that's exactly what it is.

Perhaps you can show us where the evidence is for the Egyptian knowledge of the square root of 2 or 3 or 5 or 7 or 8?

This was for a god, who was the son of a god and the father of the gods.  If it was significant, then it would be repeated for the other god-kings and later for the nobles.  A good example of this is the Pyramid texts or the use of the opener-of-mouths and so forth.  If it's supposed to be special and significant, then you need to explain (culturally) the lack of consistency.

That doesn't show that they knew square roots, but it may show a preferred proportion.  We know that they did these calculations 2,000 years later but they did not associate them with anything religious as far as we can tell.

They could do this. The left edge is 1 unit, either a remen or a cubit, whichever is required. The top and bottom lines are sqrt 7 at the first red line and sqrt 19 at the second red line. Does this look like it requires a knowledge of advanced mathematics? If anyone doubts my theory then please explain why the coffer is sqrt 19 cubits long instead of a nice even 5 cubits like Khafre's.

Khafre was taller.

Seriously, you're gonna have to compare to more than one other sarcophagus.  You have to show these square roots all over, not just one sarcophagus.

Unless you want to claim that Khufu was the Square Root King.

While you're at it, calculate 22/7, then compare that number to the "pi calculation" that the fringe love so much and note the error.  Then compare the woo calculation of the pyramid "pi" to pi itself and note that error.

Which error is greater? What is the percent difference from pi for each number?

There is no significant error in the GP pi pyramid. As I stated before, a perfect pi pyramid with a height of 280 cubits would have sides of 439.82 cubits. You wrote the following on my pyramid heights thread;

From Petrie;

North Side...... 9069.4 inches...... 439.84 Royal Cubits

East Side........ 9067.7 inches ..... 439.75 Royal Cubits

South Side ......9069.5 inches ......439.84 Royal Cubits

West Side .......9068.6 inches ......439.81 Royal Cubits (all four rounded to nearest hundredth)

That looks like they got it right, to within 2/100s of an inch, on two sides and 1/100th of an inch on one. The side with the largest error was off by a whopping 7/100ths of an inch. Shame on them. If they had used 22/7 the sides would have been 440 cubits, which apparently they are not.

They changed the slope, you know.  Had to do with the stability of the materials.

So, you decided not to compare the two "pi's?" Is that it?

Why do you claim it's a "pi pyramid" yet refuse to compare the calculations made by the fringe to the values of pi and 22/7?

The fringe calculation: 2 times a base length divided by the height. This is where the claim of pi actually comes from - a random series of arithmetical operations.
Base length: 230.38 meters
Height: 146.6 meters.

Carry enough decimals to compare:

pi = 3.1415926535897932384626433832795
2/7 = 3.1428571428571428571428571428571
The woo calculation: 3.1429740791268758526603001364256

Perhaps you'll notice exactly how close to 22/7 the woo calculation comes and that it differs far more greatly from pi than it does from 22/7

Remember, I already told you that the AE's constructed angles by a specific number of fingers "in" (horizontally) for every cubit "up" vertically.  That they measured angles this way is an established fact. The GP was constructed at an angle of 22 fingers in for every one cubit (28 fingers) up.

Since the "in" applies only to half the side length (the pyramid vertex aligns with the center of the structure,) you should be able to see that the ratio of 2 bases to one height has four times the number of base lengths as the actual Egyptian calculation of 22/28. (Two base lengths [woo]compared to one-half base length [AE's].)
So (4x22)/28 = 22/7 and there you go.

No "pi pyramid" at all.

Makes perfect sense, since the AE's didn't know pi until the Greeks gave it to them.

You should have done this yourself.  I pointed it out. Why do I have to calculate this for people every time it comes up?

Be that as it may, the side lengths are still not 440, as they would be if it were a simple 22/7 pyramid. You can't explain that. And the seked thing is from much later than the 4th Dynasty. Only the priests of Giza knew the secrets of making a pi pyramid. And Khafre was not taller. He was exactly the same size as his pappy so why did his pappy have a coffer that was sqrt 19 cubits?
