Aah, good ol' tetrahedron. Simple, reliable, stuffed to the gums with nice geometrical properties... and still the #1 among Plato's solids, after all these centuries! (^_^)
I'm far less impressed by that common-looking parallelepiped next to it. Looks utterly devoid of interest to the discerning mind. ;-)
Perhaps Pascal means Rectangular Parallelepiped which refers to a shape in which each of the faces is a rectangle (and so each pair of adjacent faces meets in a right angle); this more restrictive type of cuboid is also known as a right cuboid, rectangular box, rectangular hexahedron, right rectangular prism, or rectangular parallelepiped.[1]
"All my pencils are yellow.""Perhaps Pascal means Rectangular Parallelepiped" Oh, it was a rectangular one? Hadn't graced it with enough of my valuable attention to notice. ;-)
But truth be said, I've always liked that name: "Regular hexahedron" sounds way cooler to say than plain "a cube". "Go on, manually propel the binarily-adorned regular hexahedrons and try to exit incarceration by attaining a paired result". (Translation for non-geeks: "Try to roll a double with the dice so you can get out of jail for free.") (^_^)

I don't think it would work here. All my pencils are yellow.

Leave it to Steve to make a femal one ;-)

That doesn't look all that simple to me.
10 parts? One or two should be enough.

P.S.: "common-looking parallelepiped" is of course not the same as "common parallelepiped". :-)
