Is a rectangular pyramid is a polyhedron?
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 what Is a solid with all flat surfaces enclosing a single region of space?
A polyhedron.
What solid figure has flat faces that are polygons?
A solid figure that has flat faces that are polygons is called a polyhedron. Polyhedra have various forms, such as cubes, tetrahedra, and octahedra, each defined by the shape and number of their polygonal faces. The faces of a polyhedron are connected by edges, and the points where the edges meet are called vertices. Examples include regular polyhedra, where all faces are identical polygons, such as the Platonic solids.
What is a polyhedron with all faces the same all faces are equilateral triangles and has eight faces?
tetrahedron
What is a polyhedron that has 6 faces all faces are congruent all faces are squares?
It's a cube.
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.
Why is all the faces of a polyhedron flat?
It is a definitional requirement. If any face is not flat, then it is not a polyhedron.
Are all faces of a polyhedron flat?
Yes
Which solid shape has all flat faces?
A polyhedron.
What kind of polygon is a cube?
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.
Which which solid figure that has 4 flat surfaces that are triangles Solid figures that has 4 flat surfaces that are triangles?
The solid figure that has 4 flat surfaces that are triangles is a tetrahedron. A tetrahedron is a polyhedron with four triangular faces, six straight edges, and four vertex corners. Each of the four faces of a tetrahedron is an equilateral triangle, making it a regular polyhedron.
Is a rectangular pyramid is a polyhedron?
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 what Is a solid with all flat surfaces enclosing a single region of space?
A polyhedron.
What is polyhedron's definition?
a 3d object made of 2d faces with all flat sides
Is the shape of the football polygon?
No because a polygon is a plane figure. A football is a bit like a polyhedron, but all the faces of a polyhedron must be flat and, because of inflation, those of a football are not.
What is a polyhedron whose faces are all equilateral tringles and it has eight faces?
An eight-face polyhedron is called an octahedron.
