Close, and it's a pretty good eye-opener. Actual is given as 29.9791666... degrees to the nearest second (.0002777... degrees). Since an ideal second is defined as 10000km/90/60/60 it is 30.864+ m. The pyramid is 230.6~ m at base (7.5- seconds). So it would appear the coordinate given is within the pyramid compound, but so would a lot of other coordinates because it's too specific to be meaningful. (A ten-millionth of an ideal degree would be 1.111... cm, so the overspecified coordinate only refers to a single square centimeter somewhere on the pyramid, which shifts easily with tectonics. Since the pyramid is north-aligned to the nearest degree, treating it as 230.6m north-south yields exactly 20754 ten-millionths of the idealized degree, and the "exact" coordinates are overspecified by 4 orders of magnitude.)

Now let's imagine that (1) the speed of light hasn't changed in the past, (2) the ancients measured it at 647600 ideal earth circumferences per day, to 4 significant figures, (3) they divided this by 6, three times, to get ~2998, and (4) they deliberately constructed their pyramid at 2998/9000 of the way up from the equator to the pole, or 29.98 degrees north, that exact coordinate would also describe the Pyramid if the geo link is correct to the nearest second. That means, if they intended this coincidence, the odds of picking the right latitude among all latitudes would be only 1 in 9000, or even 1 in 5000 or 1 in 1440 if other assumptions are used, and not the apparent 1 in a billion.

To state the math in a more likely fashion, if they noticed that 647600 is close to the very factorable number 648000, it would be more a matter of starting from the salient 30-degree latitude, and going just far enough to the equator (1/1500 of the distance, or 1/1620 if they want to be closer) to match the shortfall of light in earth circumferences (a factor of 1/1620). Now the early Egyptians did not have a lot of these other math terms worked out on papyrus, but we know the later Egyptians were much better at unit fractions than we are, which is why I frame it that way. It would be much more natural to speak of 1/1620 south of 1/3 north of the equator than any other form, and to say that light is also short of a perfect 648000 revolutions by 1/1620. That calculation does flow through to the 9-digit match to one of the hundred millions of square centimeters that happen to be in the pyramid. The shortfall of the measured speed of light from exactly 3*10^8 m/s is about the same ratio (1/1445) for the same reason. Note that a large number of other ways of making the same correspondence could be done, but if you recognize that your part of the earth controls the area around the 30-degree circle that's the one you'd pick.

Since this is Conspiracies, I note that (a) all these calculations also work on a flat earth measuring lightspeed on earth's surface only; (b) they would also work in a lightspeed decay theory IF what was measured was not exactly lightspeed but a radioactivity ratio that does remain constant; there are ways to get that to fit. I'm omitting much data about lightspeed decay of course, not to mention ....

TLDR: (1) Even if lightspeed isn't constant, the agreed number is physically significant. (2) The number does match to the pyramid in the given notation but only about 4 digits are significant. (3) Using math more the way Egyptians would, this coincidence can flow from two testable assumptions: (a) They measured the speed of light as being 20^2 earth revolutions short of being 3^4 * 20^3 per day (647600 circumferences per day), and (b) They deliberately placed the pyramid with an equal-ratio shortfall of 1/(20 * 3^4) from 1/3 of the distance from the equator to the north pole (29.98- degrees north).

Congratulations! Most people who submit math here are easily debunked, but yours checks out, even if not as spectacularly as this presentation makes it sound.
