Seked

December 16, 2012 Leave a comment Go to comments

If a pyramid is 250 cubits high and the side of its base 360 cubits long, what is its seked?


Take half of 360; it makes 180. Multiply 250 so as to get 180; it makes 1/2 1/5 1/50 of a cubit. A cubit is 7 palms. Multiply 7 by 1/2 1/5 1/50:

\begin{array}{l|lll} 1&7&&\\ 1/2&3&1/2& \\ 1/5 &1&1/3&1/15\\ 1/50&&1/10&1/25 \end{array}

The seked is 5 \tfrac{1}{25} palms [that is, (3+1/2) + (1+1/3+1/15) + (1/10+1/25)].

The question for the reader, after going carefully over the English translation is: What does seked mean?
