From Petrie:

... The position of the King's Chamber in the Pyramid is defined thus: N. wall at base 330.6 ± .8 S. of centre of Pyramid; S. wall 537.0 ± .8 from centre; E. wall (284.4 ± 20.7) = 305.1 ± 3.0 E. of centre; W. wall 107.7 ± 3.0 W. of centre. Base of walls 1686.3 to 1688.5 ± .6 above pavement; actual floor 1691.4 to 1693.7 ± .6 above pavement; ceiling 1921.6 to 1923.7 ± .6 above pavement. ...

The base of the "King's Chamber" is, according to Petrie somewhere between 82.03 and 82.14 + or - .6 or anywhere from 81.43 to 82.74 cubits with an average about 82.085 cubits. Now it is safe I think to assume we could be looking at a distance of 82.00 cubits "exactly" for the floor and this yields some interesting math.

Firstly 82 cubits is, when divided by 280, = 3.4146341463414634146341463414634

However square root of 2 is 1.4142135623730950488016887242097 add 2 and we get 3.4142135623730950488016887242097 ----- Divide this into 280 and we get 82.0101013

So the "King's Chamber" sits at the point where the ratio is square root of 2 + 2 to 1

or 3.41421 to 1

Amazing as always.
