It has been proposed that the dimensions of the Earth can be derived using the perimeter of Khufu's pyramid:

Here the perimeter is multiplied by 43,200 ( the number of seconds in 12 hours).

But this equation is not very accurate.

The outcome after being divided by 2 pi is 6,335.5 km.

But the polar radius of the Earth is 6,356.8 km.

In the following video I show how the Giza pyramids were planned so as to encompass the exact polar radius of the Earth. No need to multiply by exotic numbers.

What is used is the scaling factor that converts from Greek mountains to Giza pyramids. More can be found in my books "Amphion's Secret" and "The Giza The Giza Mountains of Sinai".
