Irregulare corporis octocedron in m

Irregulare corporis octocedron in mensura ponere. Si quodlibet latus cuiusque basis ipsius per medium secetur, rectis protractis piramidibusque amotis (que sunt 6 sicut est numerius angulorum solidorum) relinquuntur in basibus tot trianguli equilateri quot prius, sed minores. Quilibet enim horum est quarta pars sui trianguli principalis, igitur corpus 14 basium inequalium 6 contra 8 procreatur. Et inter 3 tetragonas semper unus triangulus est inclusus. Cuius mensura ad instar precedentium erit nota. Quare propositum.

Octocedron irregular body lay in the measure. If you cut through the middle of each side of each base lines drawn piramidibusque removed (which are, as is the number of solid angles 6) left with the bases equilateri many triangles as before, but they are smaller. Each of these is the fourth part of the main triangle, the base body 14 8 6 against unequal quality. And always one of the quadrangles 3 is enclosed in a triangle. The measure, to be known as those who preceded them. Why plan.
