OOO! thank you! I have a use for parallelepipedal I have a a small wooden puzzle that is a striped parallelepipedal knick-knack when assenbled-- and difficult to pick up with out disassembling-- and after guests have tried for 30 minutes or so-- i take it from them, assemble, and put away-- I love 3-D puzzles.

I always just called it a "squished square" shape! (when i really meant cube for square!)
