# Surface

A surface is a two-dimensional piece of three-dimensional space.

Surface is a middle school-level concept.

### Examples

 Cone: A cone is a pyramid with a circular cross section. Cylinder: A cylinder is a solid of circular cross section in which the centers of the circles all lie on a single line. Möbius Strip: A Moebius strip is one-sided nonorientable surface obtained by cutting a closed band into a single strip, giving it half a twist, and then reattaching the two ends. Sphere: A sphere is the set of all points in three-dimensional space that are located at a fixed distance from a given point. Surface of Revolution: A surface generated by rotating a two-dimensional curve about an axis. Torus: A torus is a closed surface containing a single hole that is shaped like a doughnut.

### Prerequisites

 Parametric Equations: Parametric equations are a set of equations that together express a set of quantities as explicit functions of a number of independent variables, which are known as parameters.
