LOL, by (they) I assume you are referring to The Ancient Egyptians having no knowledge of feet and/or inches? Are you so absolutely sure they did not know of or use inches? That the cubit is derived using feet and inches is clearly spelled out by G1 in the concepts employed for the design and construction of the structure. The digit of .737inches is the basic unit of measure, illustrated by the cubit rods demonstrated divisions showing 16 additional subdivisions for a length of 0.04602272727..inches. Of course we know the AE worked in fractions not decimals, by expressing AE concepts in decimals one misses the nuances of their system. In fractions the digit becomes 81/110 inches, the 1/16 digit subdivision becomes 81/1760 inches. G1 base 9072 /440 /28 /16 = 81/1760 inches, in unit fractions (81/1760) = (1/32 + 1/110 + 1/176) inches.
