A Platonic solid?
Polyhedron is a geometric solid in three dimensions with flat faces and straight edges.

geometric solid
a polyhedron * * * * * That is only if it is bounded by plane faces. A sphere, for example, is a three dimensional shape but is not a polyhedron: it is a solid shape.
A polyhedron is a solid shape with many sides. The word "polyhedron" does not specify a number of sides.
A polyhedron is a solid shape with four or more polygonal faces. A hexahedron is a solid shape with six polygonal faces and so is a particular type of polyhedron.
A cube is a solid figure called a polyhedron. A polyhedron is a solid figure with all flat faces. So a cone would be a solid figure but not a polyhedron becasue it has a curve and does not have all flat faces.
A triangle is not a polyhedron. A triangle is a two-dimensional figure, and a polyhedron is a three-dimensional solid. An example of a triangular-shaped polyhedron is a pyramid.
I don't know if this is correct.In geometry, a polyhedron is a three-dimensional solid formed from flat planar faces with straight edges. For a regularpolyhedron, each side has the same shape and dimensions.

It is Greek for "having many bases".In geometry, a polyhedron is a three-dimensional solid formed from flat planar faces with straight edges. For a regularpolyhedron, each side has the same shape and dimensions.
