20 sided polyhedron?
A 20-sided polyhedron is called an icosahedron. It has 20 equilateral triangle faces, 30 edges, and 12 vertices. It is a regular convex polyhedron with rotational symmetry.
Is there a decahadron in nature?
No, a decahedron is a ten-sided polyhedron, which is a geometric shape. It is not a naturally occurring shape in nature.
What do you call the three sided piece of glass that separates white light into the different colors?
A "prism". Note: Prisms actually have five sides. There is no three-sided polyhedron.

What do you call a polyhedron with 10 triangular faces?
In general, any 10-sided polyhedron is called a decahedron. With 10 regular triangles for faces, you may have a pentagonal bipyramid.

What is a 60 sided polyhedron called?
I believe it called a Bucky Ball. After Buckminster Fuller.
What is a 400 sided polyhedron called?
A 400-sided polyhedron is called a "tetrahectahedron," though this term is not commonly used. In general, polyhedra are named based on the number of their faces, and for a 400-sided polyhedron, the prefix "hecta-" denotes its relation to the number 100. However, practical applications and discussions usually involve simpler polyhedra with fewer faces.

a polyhedron (if the shape is 3 dimensional) a polygon if it is a planar shape.
What is a 7 sided 3d shape is called?
A 2D seven sided figure is called a heptagon. A 3D seven faced polygon is called a heptahedron.
