If a pyramid (square) is 93 1/3 cubits high and the side of its base is 140 cubits long, what is its seked? [Hint: Given an isosceles triangle of base s and height h, we know that its seked equals s/2h, or the cotangent ratio of trigonometry. The seked in this problem has been associated with the slope of the lateral faces of the Second Pyramid at Gizeh.]
