x_{1} is a block [3-dimensional shape/form] of material x_{2}, surfaces/sides x_{3}.

x_{3} sides/surfaces should include number, size, and shape; also polyhedron (= pitybli having flat/planar sides/surfaces).
regular polyhedron (= kubybli, blikubli), brick (= kitybli); See also tapla, kubli, tanbo, canlu, kojna, sefta, bolci, kurfa, tarmi.
