nonagon
A hexagon has 6 sides and 6 angles. The prefix comes from the Greek 'hex' for six.
The prefix hept- comes from Greek "hepta" and means "seven." The prefix "sept- comes from the Latin "septem," which means "seven." The correct English name for a 7-sides polygon is "heptagon." Those who do not understand that English polygon names are derived from Greek, not from Latin, sometimes incorrectly name a 7-sided polygon as a septagon.
The answer really depends on what is meant by a three dimensional hexagon. The following are options for regular shapes. 1. The word polygon comes from Greek and the suffix "gon" refers to angles. If you think of a six-angled 3-d object, it would be two pyramids with their square bases joined together. 2. If you are thinking of a 3-d object with six faces, then it is a cube. 3. If you are thinking of a 3-d object each of whose faces is a hexagon, the answer is that such a figure cannot exist. The solid will "collapse" into a 2-d tessellation. The nearest you can get is the truncated icosahedron which is the shape of a soccer ball (or the C60 Buckminsterfullerene molecule). It comprises 12 regular pentagonal faces and 20 regular hexagonal faces.
A polygon is a closed shape with straight sides. The number of vertices a polygon has is equal to the number of corners or points where the sides meet. For example, a triangle has 3 vertices, a quadrilateral has 4 vertices, a pentagon has 5 vertices, and so on. In general, an n-sided polygon will have n vertices.

I believe is a heptagon after a hexagon and after a heptagon is a octagon.
Pentagon
Geometric figures in a plane can be 3-sided (triangle), 4-sided (square, rectangle, or, in general, quadrilateral), 5-sided (pentagon), 6-sided (hexagon), 7-sided (heptagon or septagon), 8-sided (octagon) and on and on in the polygons.
From Latin No. of sides ; Shape name. 3 ' Trigon (Triangle) 4 ' Tetragon (Quaderilateral) 5; Pentagon 6; Hexagon 7; Heptagon 8; Octagon 9; Nonagon 10l Decagon. NB Mathemtics uses are lot of names from the Classics, (Latin, and Classical Greek). That's were the above nomenclature comes from. NNB The word 'Mathematics' is from Classical Greece, and means 'to learn'.
I suppose its Hexagon.
A pentagon has 5 sides. A hexagon has 6 sides. The penta- prefix comes from the Greek for 5; The hexa- prefix comes from the Greek for 6. The -gon suffix comes from the Greek for "corner" or "angle". Thus a pentagon is a five cornered (or five angled) shape; and a hexagon is a six cornered (or six angled) shape.
After hexagon comes a heptagon, which is a seven-sided polygon. The prefix "hepta-" denotes seven in Greek, just as "hexa-" denotes six. Each additional side added to a polygon increases the number of sides by one, following the pattern of polygon naming based on Greek numerical prefixes.
The word pentagon comes from the Greek word pentagon on
nonagon
hectagon
The word "octopus" shares the same prefix as "octagon," which is "octo-." This prefix means "eight" in reference to the number 8.
