plane
A flat surface extending in all directions is a plane.
A flat surface that extend infinitely in all directions is called a plane.
If the bar is a three dimensional object it will have some thickness. Then, assuming it is oblong in shape and knowing its length, width and thickness: Surface_area = 2 x (length x width + width x thickness + thickness x length)
A plane is a flat surface with no thickness. Our world has three dimensions, but there are only two dimensions on a plane.

A plane. Or, to be more exact, an infinite plane.
A plane is a flat surface with no thickness
A flat surface extending in all directions is a plane.
A continuous mark made on a surface by a moving point is known as a "line." Lines can vary in length, direction, thickness, and shape, and are fundamental elements in art and design. They can convey movement, direction, and define boundaries or shapes.

The troposphere is Earth's densest atmospheric layer, containing approximately 75% of the atmosphere's total mass. It is the layer closest to the Earth's surface, extending up to about 7-17 kilometers in altitude.
The exosphere is the outermost layer of Earth's atmosphere, extending from about 500 to 10,000 kilometers above the planet's surface. It gradually fades into outer space and its thickness is not clearly defined due to its thin and sparse nature.

Light oscillates in a direction perpendicular to the surface of the shiny transparent surface when it is reflected. This is known as the normal direction.
