Imperial measure; Petrie must have guessed his measurements of the coffer matched imperial perfectly.
Fortunatly the coffer within the second pyr has a lid. So lets begin our investigation from the top.
Lid 103.7 x 42.0 x 9.9 inches.
Length of coffer 103.68 inches however in Petrie's day 103.68 inches may not have drawn the same significance as today.
Height of coffer minus lid 38.12 inches.
Height of coffer with lid 48.02 inches
Lid length 8.64 imperial feet sacred number twice 432.
Lid Height 9.9 inches known as a 'Great span' and a Welsh foot.
Width 3.5 feet
Height of coffer total 48 inches 4 imperial feet.
The volume of the outside of the coffer is 4 x 3.5 x 8.64 = 120.96 cubic feet a sacred number 1296.
The volume of the outside of the coffer is connected to the volume of the coffer by the Babylonian value for pi 3.125 or 3 1/8th found on a clay tablet near Susa in 1936.
120.96/ 3.125 = 38.7072 cubic feet the inside volume of the coffer Exactly. And this inside volume is most probably intended to be 1/2,020,000th the volume of the pyramid itself.
The Great Pyramid coffer volume is 1/2,200,000th the volume of the Great Pyramid and I think one of the purposes of this is to record in a volume measure the AVERAGE (they are all different sizes)number of building blocks in each pyramid.
Anyway the point of all this is if the outside measurements of the coffer in the second pyramid are in inches and feet why not the pyramid itself?
Draw your attention to the inside length of the coffer and base measurement for pyramid if you decide to do some drawings it may give you a clue.
