Steinhaus puzzle (a variant of Soma Cube) — assembled

Made from Robert Neale’s penultimate module (3×44 + 3×36 = 240 modules).

 

This puzzle, described in Hugo Steinhaus’ book Kalejdoskop matematyczny (Mathematical kaleidoscope) consists of six pieces, which can be assembled together to form a cube (as in the first image) or a variety of different shapes (such as the one shown in the second image). All separate pieces are shown in the last image. A similar puzzle, better known in the English-speaking world, is the Soma cube. As you can see, Steinhaus’ version uses slightly different shapes for the individual pieces, for example there is no P-piece (the one that consists of one big cube’s vertex cube and three adjacent cubes).
