Quote: "Everyone is always trying so hard to understand dimensions above 3d, but what about learning more about 2d. I don't understand the concept of 2d at all. If you think about it hard I think you will have a huge amount of trouble to make sense of it. Since a 2d object only has 2 dimensions, like it could have width and lenght, but that means it wouldn't have height so if it doesn't have height then how are we supposed to see it, it is like an imaginary plane to us. You might like to think of a 2d object as a piece of paper, but instead of the very small height that paper has a 2d object has infinatly small height. Anyone like to explain a bit about this concept. I realise I may be talking a load of s$%t but this is the concept that I can come up with logics."
2D is width, and height, not width, and length.
3D is width, height, and depth.
