what is a 2 dimentional shape?

Something that has height (length) and width . . . and no depth.\n\nDraw a square on the piece of paper. That square is two dimensional . . . if you draw a cube . . . it shows a third dimension (depth).

The edges are anywhere that 2 of the surfaces connect.  If you are given enough information, say the coordinates of one of the corners and some combination of length, width, height, surface area or volume, you should be able to draw it in 3-dimensional space.

Why are you asking this again?  I just answered you.\n\nAgain:\nThere are "levels" to dimensioning.\n\nThe major dimensions are the overall height, width, depth of the whole object. \n\nThe next level down will sub-divide that major dimension to describe sub-components.\n\nAs example: Consider a house plan. \n* From one extreme side to the other extreme side is a MAJOR dimension (the overall width). \n* In between those extreme outer wall edges are interior walls that need to be located as well. So the next layer of dimensions (MINOR) still goes from one side to the other but pulls lots of dimensions from lots of walls. \n* Also, there are porches, corners for inset windows, etc Another MINOR level picks up those points.\n* And so on.\n\nIn your 3D drawing: \n* you only have 6 MAJOR dimensions to a cube shape anyway. Depending on how you rotate the drawing object, you see 3 of them and 3 will be hidden (back side).

you need to know the radius to answer diameter. \n      2\n     R =D  r to the power of two equals D\n\nR=radius D= diameter

If you're familiar with 2 D coordinates, 3 D coordinates should be no problem.  2 dimensions (with 2 (x,y) coordinates needed to describe a point) describe a flat surface (area) with length and width.  3 dimensions describe a space (volume) length, width and depth.  To describe a point 3 (x,y,z) values are needed.  4D adds time so that 4 values are needed to describe a point (in time).  Trigonometry and linear algebra become very important and helpful to solve problems.

Cool geometry im learning this in class 2bad i cant help u cuz im faling -.-

triangle area = 1/2(height * width)\n\ncircle area = pi * radius^2

I can't answer your question, but want to point out that accordig to everything I've heard:\n\n2nd is a flat dimension.  As is 2 dimensional.\n3rd is what we live in now.\n4th is Time Travel.\n OR\n"Seeing that Meg remains confused, Charles Wallace explains that tessering is travel in the fifth dimension: the first dimension is a line; the second is a square; the third is a cube; the fourth is Einstein's concept of time; and the fifth is a tesseract. By adding the tesseract to the other four dimensions, they travel in such a way that the shortest distance between two points is not a straight line."\nhttp://www.sparknotes.com/lit/wrinkle/section5.rhtml\n\nTo better understand some of what the dimensions are in the first place, I would read Wrinkle In Time, A Wind Through The Door, Many Waters, and Swiftly Tilting Planet (The Time Quartet.) by Madeleine L'Engle.

an A3 piece of paper has a width of 29.7 cm and a height of 42 cm.\nIt's as big as two A4 sheets placed side by side (just like the A2 is as big as two A3 sheets place side by side and so on...), since a A4 piece of paper has a width of 21 cm and a height of 29.7 cm.

The perimeter of a shape is the distance around it (add up all the sides.)\n\nAn 'object' is 3 dimensional and does not have a perimeter as such. 'Perimeter' usually applies to 2-dimensional shapes only.

In geometry, a rectangle is defined as a quadrilateral polygon in which all four angles are right angles.\n\nFrom this definition, it follows that a rectangle has two pairs of opposite sides of equal length; that is, a rectangle is a parallelogram. A square is a special kind of rectangle where all four sides have equal length; that is, a square is both a rectangle and a rhombus. A rectangle that is not a square is colloquially known as an oblong.\n\nOf the two opposite pairs of sides in a rectangle, the length of the longer side is called the length of the rectangle, and the length of the shorter side is called the width. The area of a rectangle is the product of its length and its width; in symbols, A = lw. For example, the area of a rectangle with a length of 5 and a width of 4 would be 20, because 5 × 4 = 20. See the picture above right.

If it's 2-dimensional, it's a decagon.  If it's 3-dimensional, it's a decahedron.

Problem one's answer is 1 inch as you guessed.\n\nProblem two, the answer is : 24 by 36 feet\nHere is how to get it...\nAs seen in the previous problem, each inch on the paper is 2 feet in real dimensions.\nso we just multiply each inch by 2.

There are in infinate number of 2d shapes, but here are diagrams of some of them --> http://www.mathleague.com/help/geometry/polygons.htm

polygons are 2 dimensional shapes. they must have all straight sides and they must be closed. some examples are squares triangles, etc.  circles aren't because they  have 1 curved side.\n\npolyhedrons are 3-d shapes that have all flat sides and have no openings. ex: cube. spheres, cones, and cylinders are not because they all have curved sides.
