Question

What has a flat surface that extends infinitely, has length and width, but does not have depth?

Answer 1

Answer:

A flat surface that extends infinitely, has length and width, but does not have depth is a Plane.

Explanation:

A plane extends infinitely in two dimensions. It does not posses any thickness. An example of a plane is a coordinate plane.We graph points in the coordinate plane, which is an example of a geometric plane. The coordinate plane has a number line that extends towards left to right indefinitely and another one that stretches up and down indefinitely.There are many types of planes like parallel planes, intersecting planes.  A plane is denoted by the upper case Letter P in a cursive format.
