The base word for a many sided figure is polygon.All four sided polygons are called quadrilateralThe sub groups of planar (2 dimensional) quadrilaterals are:-rectangle (a special kind of parallelogram)square (a special kind of rectangle (rhomboid))trapeziumrhombus (an equilateral quadrangle which must also be a parallelogram)parallelogramThese are also called quadrangles (as they have four angles as well as four sides).A three dimensional shape with four faces (surfaces) is called a tetragonTetragons have six edges and four vertexes, each where three edges and three faces meet. A triangular pyramid is a tetragon. it is the simplest three dimensional shape.
Solid Geometry
A cube could be described as a box, or as a three dimensional square.
Solid figures are normally classed as 3 dimensional objects
The question is ambiguous. An octagon is a 2-dimensional shape with 8 edges and 8 vertices. Does a 3-D octagonal shape mean one with 8 edges or 8 faces or vertices, or faces which are 2d octagons?
Figures in three dimensions are known as solids.
A cube.
A cube
then it's a - Dodecahedron
you look at the base so that will be the first name andd the figures beside the base will be either a prism(rectanular) or a pyramid(triangular), you find out which one is that, and then that's the second name(ex; its shaped triangular, and the base is a hexagon then the three-dimensional figure will be called a hexagon pyramid...

There are infinitely many types of 3 dimensional figures. It is impossible to name them all.
