What is a frace on a polyhedron?
The face of a polyhedron is any of its flat surfaces
What are the flat surfaces of a polyhedron called?
faces
Can a polyhedron have either flat or curved surfaces?
false
What is a the three-dimensional object with flat surfaces?
A polyhedron.
What are the flat surfaces on a pyramid cube or rectangle prism called?
flat surfaces on any polyhedron are called faces
What are three-dimensional shape with flat surfaces that are polygons?
Polyhedron (plural polyhedra)
A what Is a solid with all flat surfaces enclosing a single region of space?
A polyhedron.
Is it true that solids having flat surfaces that form into polygons are polyhedron?
true
Why are the flat surfaces on a rectangular prism called faces?
The flat surfaces of all polyhedra are called faces and a rectangular prism is simply one kind of polyhedron.
Is every polyhedron a solid?
No. By definition a polyhedron has to have faces (flat surfaces), edges, and vertices. A sphere, hemisphere, and a cylinder are all solids but are not polyhedra.
Are the faces of a polyhedron all flat surfaces?
Yes and its flat surface faces are in regular shapes.
What is the difference between a polyhedron and a non-polyhedron?
A polyhedron is a three-dimensional geometric shape with flat polygonal faces, straight edges, and vertices, such as cubes and pyramids. In contrast, a non-polyhedron includes shapes that do not fit this definition, such as spheres, cylinders, and cones, which have curved surfaces and do not consist entirely of flat faces. Essentially, the key difference lies in the presence of flat polygonal faces in polyhedra versus the curved surfaces in non-polyhedra.
