Low-Tech Armor with the Strength of Ten Men

[DemiBenson]

Using only LT armor (and Pyramid) and aiming for some realism, how thick could you get armor if the warrior was magically "as strong as ten men" (that is, has ST 30-33 range). Assume it's magic or divine gift, so the warrior is the size/bulk of a normal person, and not as bulky as ten men.
