All 2-dimensional shapes.
They may be closed or open, concave or convex, made of straight lines or curved ones, the lines may or may not cross each other.
Length, width, vertices (corners), sides, thickness.
A 3d shape is a forms of shapes that have length , width and death of thickness.
2d shapes only have length and width, while 3d shapes have length, width and depth.
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 figure
Length, width, vertices (corners), sides, thickness.
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.
A 3d shape is a forms of shapes that have length , width and death of thickness.
Time has no length, width or thickness.
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.
The answer is 12,553 m.
A point.
2d shapes only have length and width, while 3d shapes have length, width and depth.
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)
In geometry three-dimensional shapes are solid figures or objects or shapes that have three dimensions length, width, and height. Unlike two-dimensional shapes, three-dimensional shapes have thickness or depth. A cube and cuboid are examples of three-dimensional objects, as they have length, width, and height.
