An octagon is a 2 dimensional shaped 8 sided polygon
Books, boxes, notebooks, and basically every three-dimensional figure with rectangular sides.
An egg-shaped, three-dimensional shape is an ovoid.
A seven sided polygon
It would be a dodecagon.
An ellipsoid is a three-dimensional egg-shaped figure.

probably a sphere
There are many but I guess that the answer that you are looking for is a pyramid.
A seven sided polygon in called a heptagon.
If it's three dimensional, a 12 sided figure is a dodecahedron.
It is a polygonal pyramid.
A triangle is not a polyhedron. A triangle is a two-dimensional figure, and a polyhedron is a three-dimensional solid. An example of a triangular-shaped polyhedron is a pyramid.

Yes. A lot like a sphere actually, but a big one.
