What is a 5 sided 3d object?
In geometry, a pentahedron (plural: pentahedra) is a polyhedron with five faces or sides.
What is a polygon in 3d called?
A three-dimensional shape whose faces are polygons is known as a polyhedron. This term comes from the Greek words poly, which means “many,” and hedron, which means “face.” So, quite literally, a polyhedron is a three-dimensional object with many faces.
What is a 5 sided polygon called?
pentagon
A pentagon is a geometrical shape, which has five sides and five angles. Here, “Penta” denotes five and “gon” denotes angle. The pentagon is one of the types of polygons. The sum of all the interior angles for a regular pentagon is 540 degrees.
What is a 5 sided pyramid called?
In geometry, a pentagonal pyramid is a pyramid with a pentagonal base upon which are erected five triangular faces that meet at a point (the vertex). Like any pyramid, it is self-dual.

What is a regular 3D shape?
A regular polygon is a (convex) planar figure with all edges equal and all corners equal. A regular polyhedron is a solid (convex) figure with all faces being congruent regular polygons, the same number arranged all alike around each vertex.
