They have one fewer dimension; they lack depth.
A polyhedron is a three dimensional shape. A polyhedron is bounded by a number (four or more) of polygons and encloses one space.
two-dimensionalOn a+ the answer is three-dimensional
Some do, some don't. A regular polyhedron such as the tetrahedron has none whereas an irregular one like the parallelepiped can have several.
A rectangle is a two-dimensional shape, so it doesn't have faces in the way that three dimensional shapes have. A rectangle has four edges and four corners.
None. Edges are one lines (1-dimensional) not shapes like squares (2-dimensional).None. Edges are one lines (1-dimensional) not shapes like squares (2-dimensional).None.

All of those are 3-dimensional shapes.
Ah, let's paint a happy little picture with shapes! We have the cube, the sphere, and the cylinder. Each one is unique and beautiful in its own way, just like you are unique and special in this world. Keep exploring and creating, my friend.

All three dimensional figures have more faces than a one dimensional figure. There are an infinite number of one dimensional points on a three dimensional figure
There is none because a triangle is a 2D shape and volume measures 3D shapes ----------------------------------------------------------------- There is not one. Triangles are two dimensional, volume is three dimensional, a triangle can therefore have an area but not a volume.
A line is one dimensional. All two dimensional shapes have height and width.
Three dimensions refer to the physical space in which we live, characterized by length, width, and height. Three-dimensional objects have volume and take up space in all directions. This concept is fundamental in geometry and physics.
none :)
