yes, it is...
A point has no length, width, or thickness. A line has infinite length but no width or thickness. A plane has infinite length and width but no thickness.
Time has no length, width or thickness.
A line has infinite length, no width, no thickness, and no endpoints.
Length
LxWxT typically stands for Length x Width x Thickness. This formula is commonly used in mathematics and geometry to calculate the volume or area of a three-dimensional object or space. By multiplying the length, width, and thickness of an object, you can determine its overall size or capacity.

A line has infinite length, no width, no thickness, and no endpoints.
This would be a line, which has no width, no thickness and no endpoints, but has infinite length.
Technically its width but if you are talking to someone they should know what you mean by thickness.
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)
The thickness
A point.
