A decahedron is a closed 3-D shape with ten polygonal faces. There are 32,300 topologically different decahdra and, since none of these are regular, the term is ambiguous. The formula for the volume of a decahedron will depend on which one of the 32,300 decahedra it is, and in many cases it is likely to be quite a complicated formula.

A decahedron is a solid shape with ten flat faces.
No.
A 10-faced three-dimensional shape is called a decahedron. In geometry, a decahedron can have various forms depending on the arrangement and shape of its faces, which can be polygons of different types. The most common type of regular decahedron is the regular pentagonal decahedron, which has faces that are regular pentagons.
