What is a 8 faced 3D shape called?
octahedron
In geometry, an octahedron (plural: octahedra, octahedrons) is a polyhedron with eight faces, twelve edges, and six vertices. The term is most commonly used to refer to the regular octahedron, a Platonic solid composed of eight equilateral triangles, four of which meet at each vertex.
What is a polyhedra shape?
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 3D shape has 8 vertices and all faces are congruent?
A cube or a cuboid is a three dimensional shape that has 12 edges, 8 corners or vertices, and 6 faces.
What is the 3D shape of triangle?
Triangular Prism (3D shape with identical triangle bases)
What are the 3 main characteristics of polyhedra?
In geometry, a polyhedron (plural polyhedra or polyhedrons) is a three-dimensional shape with flat polygonal faces, straight edges and sharp corners or vertices.

What makes up the face of a 3D shape?
3D Shapes. A face is a 2D shape that makes up one surface of a 3D shape, an edge is where two faces meet and a vertex is the point or corner of a geometric shape. To work out the area of a face of a 3D shape, you use square units such as cm 2 as the face of a 3D shape is a 2D shape in its own right (a pyramid’s face will form a triangle,…
