It is called a decahedron.
It is called an endacehedron.
According to Euler none; for all 3d shapes: Vertices + Faces = Edges + 2 ⇒ 12 + 8 = 19 + 2 ⇒ 20 = 21 So unless 20 does equal 21, no 3d shape has 8 faces, 19 edges and 12 vertices. Any 3d shape with 8 faces would be an octahedron.
well. it is called icosahedron
It is called a Triacontakaidigon.
That 3D shape is called triangular pyramid.
A tetrahedron, also called a pyramid is a three-dimensional shape with four faces.
A three-dimensional figure with 30 faces is called a triacontahedron.
The 3d shape that have five faces would be a triangular prism **************** or a pyramid
