I don't think MMP 14 mentions the seked. It is only concerned with volume.

Gillings mentions something important about the volume formula - if you dissect a cube into six parts along its four diagonals, you get six equal volume pyramids of slope angle 45 degrees. It is from this ideal pyramid that the volume formula (V = 1/3 x b x b x h) can be taken.

The Bent Subsidiary pyramid (base 100c; height 50c; slope 45 degs) is the one pyramid that fulfills this model.

Two thousand years ago a Chinese mathematician also wrote a paper about the volume of pyramids - they built step pyramids.
