There are no regular geometric figures with 9 edges and 10 faces.. I'm not even entirely sure there is an irregular geometric figure that would allow for such a combination- edge count and face count are usually identical... Maybe if you were describing some sort of conic section but I can't figure out what that might look like.
A 10 edged (sided) shape is called a decagon.
It is called a decahedron.
A decahedron.
A shape that has 10 sides (two dimensional) is called a decagon. A shape that has 10 faces (three dimensional) is call a decahedron.
A polygon (2-dimensional shape) with 10 sides is a decagon. A 3-dimensional polyhedron with 10 faces is a decahedron.
The 3D shape with 2 octagons and 8 squares is called a truncated square antiprism. It is a type of prism where the top and bottom faces are octagons, and the side faces are squares. This shape has a total of 10 faces, including 2 octagons and 8 squares.
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.
It is an octagonal prism that has a total sum of 10 faces
A 10-sided shape is known as a decagon.(A decahedron is a 3-dimensional solid with 10 polygonal faces.)
hexagonal
octahedron - a polyhedron with 8 faces
A 3d shape with 10 sides is called a decahedron. I have added a link with some pictures of them. As you can see they look very different but all have 10 sides or faces.
