What is a 3d hexagon called?
I fancy a bash at this one. I am attracted to the fact that the question is an oxymoron. A hexagon is a planar shape. That is to say it is by definition two dimensional. Therefore there cannot be a 3d hexagon in any strict sense. However I am not a complete pedant. (I have had my tonsils out) So I am going to try and answer every question that you MIGHT have meant to ask and hope one of them is the right one. I am assuming you are referring to regular solids; i.e. solids with a given number of identical faces. Such as you find on a dice (or die if you are pedantic) Dice are of course regular six sided 3D shapes. Each face being a square. This is called a hexahedron (hexa=six, hedron=face) There are other types of dice such as a four sided one which is made up of four equilateral triangles, this is called a tetrahedron. If it helps, think of a pyramid with a triangular base instead of a square base. Put one face each of two tetrahedrons together and you get a different six sided figure
