Trace a Menkaure dimension through the published figures, the model and the calculation.

  1. 01 · Published dimensions Begin with the pair

    Lehner tabulates 102.2 × 104.6 m for the base and 65 m for the height. The first two numbers describe different directions across the base.

    Mark Lehner, The Complete Pyramids (1997), p. 17.

  2. 02 · Working model Choose a square base for calculation

    Jones uses 103.4 m as the average base in his construction model. The average simplifies a pair of dimensions to one side of a model square.

    Richard Jones, construction study (2006), p. 194.

  3. 03 · Calculation Turn half a side and a height into an angle

    arctan(65 ÷ 51.7) ≈ 51.50°

    For the square model, the run is half of 103.4 m. The calculator uses that run and the selected 65 m height.

    Repeat the calculation with the Menkaure preset.

  4. 04 · Cross-check Ask which boundary the survey describes

    Petrie makes a separate choice about where to reconstruct the casing base. Read his adopted base level and side lengths before treating the model angle as a claim about surviving stonework.

    Read the survey comparison and Petrie’s source citation.
