Why is a cylinder not a polyhedron?
A polyhedron is a 3 dimensional figure made of polygons. A cylinder is made of two circles and a rectangle around the middle. Since circles are not considered polygons (don't have straight edges), a cylinder cannot be a polyhedron. I just had a discussion about this with my math students today.
What are the flat surfaces on a pyramid cube or rectangle prism called?
flat surfaces on any polyhedron are called faces
Rectangle based pyramid?
It is a 3-dimensional shape - a polyhedron = whose base is a rectangle and which has four triangular faces attached to its sides. These free vertices of these triangles meet at an apex above the base.
What geometric shape is one of the faces of a cereal box?
A cereal box is a six sided rectangular polyhedron called a rectangular cuboid. Each of its faces has the shape of a rectangle.
Is a cuboid a polyhedron?
no a cuboid is not a polyhedron if it was it would have 9 faces
Why is a rectangle polyhedron not regular polyhedron?
The sides of a rectangle are not all equal so a rectangle is not a regular polygon. And, as a consequence, any 3-dimensional shape made from rectangles cannot be a regular polyhedron.
What are diferent names for a rectangle?
quadrilateral, polyhedron,
What is the name for a polyhedron who's bases are a rectangle?
There is not enough information to determine how many faces the polyhedron has (and therefore its name).
What are polyhedrons?
A polyhedron is a kind of rectangle. This category includes squares,circles,etc.
What polyhedron has two bases that are hexagons the other faces rectangle?
a hexagonal prism
What are some geometric shapes?
Line, Circle, Triangle, Square, Rectangle, Trapezoid, Pyramid, Polyhedron.
What could a rectangle square isosceles triangle and a hexagon polyhedron make?
The answer depends on their relative sizes and configuration.
All sided polygons and their names?
square, triangle, polyhedron, octogon, pentagon, hexagon. dihedron, rectangle,

What is the name of the shape that has four faces?
A polyhedron (solid shape formed by plane faces) with four faces is called a tetrahedron.
