"The ancient towers from the Talse Uzer Stories. They are already big on the outside, but on the inside, they are about six times as big as Earth's surface. Just how big it is. Tower of God shows the huge scale of things inside the towers pretty well."

I don't know where they got this from. It's talking about the towers of Atrakion (or flower stalks) whatever it's spelt. Whoever wrote this, must be assuming that the Tower (as in, Tower of God) is one of those because it's the same universe, and even those who clean the towers as part of a job don't know anything about those towers. There is also an uncertainty created by the fact that these towers don't have actual doors or windows

And the outter tower (residential area) of each floor in the tower is as big as the North American Continent, and it is not counting the inner tower and the middle area though those must definitely vary from floor to floor, and wouldn't be as big.

Anyway, Calculating the total number of floors that are known to exist (134~135) and adding up each outter area surface, you'd get 6.5 times the whole Earth. Well, this is what the calculation gave anyway; not that I've done it myself.

There is a post about it here on the wikia
