One dimensional is (probably) a line.
Two dimensional is a flat plain figure, showing length x width.
Three dimensional is a cubic shape, showing length x width x depth.
They have one fewer dimension; they lack depth.
Polyhedrons are three-dimensional shapes with flat faces, straight edges, and sharp corners, known as vertices. Examples of polyhedrons include cubes, pyramids, prisms, and dodecahedrons. These shapes have a closed surface and are made up of polygons, which are two-dimensional shapes with straight sides.

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.
three dimensional
two-dimensionalOn a+ the answer is three-dimensional
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 shape is typically defined by its dimensions, which indicate the extent of its geometry in space. The most common dimensions include one-dimensional (1D) shapes like lines, two-dimensional (2D) shapes like squares and circles, and three-dimensional (3D) shapes like cubes and spheres. In theoretical contexts, shapes can also extend to higher dimensions, such as four-dimensional (4D) shapes, but these are less commonly encountered in everyday experiences. Thus, the number of dimensions that make up a shape can vary depending on its classification.
A line is one dimensional. All two dimensional shapes have height and width.
Three-dimensional (what I think your talking about), is a shape with length with and height. Everything you touch and see is three-dimensional. Something two-dimensional is a shape like a square or a circle. An example of something three-dimensional is a cube, or a sphere. Something one-dimensional is just a straight line. This is difficult to explain, I'll look on my message board and this question's discussion page and answer any questions you have.
