Real ones are!
Yes, we live in a three-dimensional world where objects have length, width, and height.
Gauss's law is used to calculate electric fields in three-dimensional systems, electric flux in two-dimensional systems, and charge distribution in one-dimensional systems.
Three-dimensional things are objects that have height, width, and depth. They exist in physical space and have the ability to be viewed from multiple angles. Examples include a cube, sphere, and pyramid.
The three basic dimensional qualities are length, width, and height. They are used to describe the physical size and shape of an object in space.
A three-dimensional object is called a solid.
No. Planes are 2-dimensional.
A polyhedron is a three-dimensional object, not two-dimensional.
Some planes have only one intercept.
Impossible to answer. By definition, rectangles are only two dimensional. By extrapolation... A three dimensional rectangle would be a rectangular cube; this would have six planes.
Lines! Yes, they are one-dimensional. Points are zero dimensional, planes are two-dimensional, and prisms and such are three dimensional.
Planes figures such as polygons are not solids. Solids are three-dimensional .
The difference is that two-dimensional shapes have a length and a width while three-dimensional shapes have a length, width, and depth. While some examples of two-dimensional shapes are circle, rectangle, and triangle, example of three-dimensional figures are a sphere, cuboid, and a pyramid.
A sphere does not have any planes inside it, as a plane is a two-dimensional flat surface, whereas a sphere is a three-dimensional object with a curved surface.
No, they intersect at a line.
No, the two planes intersect at a line, which is an infinite number of points.
They are the points where three (or more) planes (or faces of the shape) meet.
It is a cylinder
