Donatello starts with a marble cube of side length 1. He then slices a pyramid off each corner, so that in the resulting polyhedron, all the edges have the same side length s. Find s.

The side length is $s = \frac{\sqrt{2}}{2}$

Sorry....I typed it backwards after working it out on paper

sqrt (2)  - 1

s + 2(sin45º * s) = 1

s = 0.414213562       or  √2 - 1
