A 20-faced shape is called a icosahedron. It is one of the five Platonic solids and is characterized by having 20 equilateral triangular faces, 12 vertices, and 30 edges. The icosahedron is known for its symmetrical properties and is often used in various fields, including geometry, gaming, and molecular Biology.
icosahedron
A six faced 3d shape is called a cube.
Oh, dude, a 20-faced 3D shape is technically called an icosahedron. It's like a fancy way of saying it's a shape with 20 sides or faces. So, next time you see a 20-faced shape, just casually drop the term "icosahedron" and watch everyone be like, "Whoa, this person knows their geometry!"
Enneahedral
A hendecahedron.
A twelve sided shape is called a "dodecahedron" :D
Decahedreon
A pyramid.
It is a nonahedron.
It is called a trihedron. It does not exist.
Dodecahedron.
A cube or a cuboid
