it is because if it were square, circular or even triangular, there would be less space for us to write on. furthermore, as paper is mass-produced, it would be easier to create rectangular paper than other shaped papers. Plus, as printers, scanners and photocopying machines are all already built to print on rectangular paper, it would be troublesome to change the shape of paper.
Yep, you got it!
A rectangular prism has 8 vertices whereas rectangular based pyramid has 5 vertices
There is no specific reason, actually. Also, I know at least one flag does not; look up Ohio's flag. (alternate answer) Rectangles are a convenient shape to work with. You might also ask why pieces of paper are rectangular, books are rectangular, newspapers and magazines are rectangular, candy bars are rectangular, and so forth. It would be trickier to make pentagonal flags. Why give yourself extra work? Switzerland's flag is a square rather than a country; I think they had to get special permission for this. Rectangular flags appear to be golden rectangles which are said to look nicer, so perhaps this has something to do with it.
Rectangular cuboid
both are a rectangular
It is a rectangular shape. If you were to roll out the whole roll it would be rectangular! And weird question! I like it! ;)
a rectangular prism (fancy word for a looking at in in 2 dimensions instead of flat on the paper)

You use only paper and your hands to fold it. You can use multiple pieces of paper, but it's not required. The paper used is mostly square, rectangular or triangular.
Money box is a rectangular prism in which one keeps paper and coin capital
With the developments of rectangular box on paper how am I supposed to find the area of the paper that I need to make the box -- Not find the air of the box itself but the paper used? By measuring the area of one side of the box and multiplying by the six sides. You get the total area of the box (Cube).
8 corners will be left
The good thing about the developments of rectangular boxes is that they are still rectangular! In order to find the surface area of the paper needed to make a box, you would first need to determine the measurements of your finished box. One you have determined your length (L), width (W), and height (H), you will need to do some simple math. 2(LxW) + 2(WxH) + 2(LxH) = the area of paper that you need to make a box.
A rectangular shape has four right angles, (90 degrees each, 360 degrees in total) and parallel (opposite) sides are equal. An example of a rectangular shape would be a piece of paper, a book, or the side of a box.
Take a rectangular piece of paper and fold it diagonally until you have a triangle that is two pieces of paper thick, Cut of the piece of paper that does not make up part of the triangle unfold it and you have a square.
A rectangular prism is a three-dimensional shape in which each of its six faces is a rectangle. Three common items that are rectangular prisms are: hardcover book, box of tissues, ream of paper.
No, a rectangular prism is a 3D object with rectangular sides and a shape with 3 or more edges on both ends. A dollar bill (or any other similar piece of paper) is a 2D rectangle.
