no it's a polygon not a polyhedron
Yes.
Yes, it is.
Yes it is as it is a third dimensional shape
Yes. A polyhedron is a geometric shape with flat surfaces and straight edges, so a a pyramid with a rectangular base qualifies as a polyhedron. It is however not a regular polyhedron, which would require all the faces to be the same shape and size. To change your pyramid to a regular polyhedron you'd have to turn it into a tetrahedron.
A polyhedron is a 3-dimensional shape whose faces are all polygons.
yes because a polyhedron is a flat shape with straight sides, for example a cube or a triangular prism.
A polyhedron is a geometric shape. It does not have the capability of doing anything.
no not all pyramids are polyhedron because each pyramid has a different shape. so no each pyramid is not a polyhedron * * * * * Yes they are.
Nope - A polygon is a flat, 2-dimensional shape. A Polyhedron is a 3-dimensional shape.
The answer is a polyhedron
Any polyhedron.
A polyhedron is a solid shape with many sides. The word "polyhedron" does not specify a number of sides.
