Sure, use a calculator, use Excel, use Mathcad, use Matlab

Make a Dodecahedron. That's what I did.

Yes, what's the question? I'll take a guess ...\n\nIf your rectangle is divided into ten equal pieces, then each one will be a tenth, so if you shade 3 for example, that will be 3 tenths ... any help?

Perhaps the illustrated link and description will help you.  Good luck with your project.

since your ddoing coordinate geometry you should at least tell what shape you're trying to get.\nI'm assuming it's a parallelogram so u should make it (1,8)

The idea is to build up the corners, you want to get a 2x2x2 corner lined up and then work from there.\n\nHere's a very helpful link\nhttp://lar5.com/cube/

Ok, so it's not a realistic barrel.  Sheesh.  It's a math problem, for crying out loud.  And, at its core, it's a conic section problem.  What you're being asked is find the dimensions of a conic section with a given volume. To do that, you need to realize what a cone and a conic section actually are.  A cone is just a right triangle spinning in a circle, and a conic section is a right trapezoid doing likewise.  There's probably a formula for getting the volume of a conic section, but I don't know it, so I find it easiest to complete the cone (draw it out to its endpoint) get the volume of the full cone, get the volume of the cone I've added on, then subtract to get just the section I'm working with.\n\nTo start, draw the conic section as a right trapezoid.  Mark the lengths you know:  the short parallel side is 9x, the large parallel end is 15x, and the perpendicular side is 35.  Then draw a vertical line down from the outside edge of the small end (the bottom of your mythical cask) to the large end, the length of which will also be 35.  This turns your trapezoid into a rectangle and a right triangle, making it much easier to deal with:\n _\nI  I&#92;\nI_I_&#92;\n\nGiven that you know that you have a rectangle, the left segment of the base of the trapezoid (the bottom of the rectangle) must be 9x, which makes the base of the triangle 6x.\n\nNow you'll put a right triangle on top of your rectangle to make the whole thing into one large right triangle.  This triangle will be similar to (that is, the sides will be in proportion with) the triangle that you made in your trapezoid.  You know that the base of your old triangle is 6x and the height is 35.  Since the base of the new triangle is 9x, the height of the imaginary triangle must be (9/6)(35), or 52.5.\n\nThe volume of a cone is 1/3(pi)r^2h.  (Remember that the base of the triangle is the radius of the circle.) You now have two cones:  the imaginary one, and the bigger one which includes both the real and the imaginary.  Figure out their volumes, and subtract out the imaginary:\nImaginary: 1/3(pi)(9x)^2 (52.5)\nBig 'un:  1/3(pi)(9x + 6x)^2 (87.5)\n\nImaginary:  1417.5(pi)x^2\nBig 'un:  6562.5(pi)x^2\nReal:  5145(pi)x^2\n(To make things easier from here on out, I'll use 3.14 for pi.\nReal: 16155.3x^2 in^3\n\nSo we know what the volume of the section is in proportion to the radii of the top and bottom.  Now we need to figure out how many cubic inches of fluid are in 39 gallons.  Taking a quick trip to a conversion website, I find that there are almost exactly 231 cubic inches to a gallon, or 9009 in^3 in 39 gallons.\n\nThe rest is fairly simple:\n16155.3x^2 = 9009\nx^2 = .558\nx = .747\n9x = 6.721\n15x = 11.201\n\nYou would normally express the size of a circular object in terms of its diameter (think pizzas or pies), so double those last two numbers to get a cask where the top is a disc of diameter 22.402 in, the bottom is a disc of 13.442 in, and the depth is 35 inches.\n\nWhew!  I'm exhausted!

Have you tried the ezplot routine?  You can get help from the context help window.  Mathlab is the bomb.

Hi I assume you mean an unsymmetrical item. I also assume you want a best fit. I have done similar things on a computer but not by hand. The computer finds three point most distant from the centroid and uses these points as pivots for three orthogonal planes. Not sure of the rest.

Build an abacus.  \nArrange 10 beads on a piece of piano wire.  Every fifth bead should be a different collor.\n--oo--oo0-oooo0--\nMake a few more strings and mount them together in parallel or inline with each other.\n------ooooxoooox\nooo----oxoooox--\n--ooooxoo----ooo\n\nA really cool math based model would be a display of geometric shapes.\n\nYou could go to the matherworld site and print out some patterns for the platonic solids.  Then cut them out and fold them together.  The collection can be displayed in a couple of ways.  The easiest would be to mount them on straws poking out from a block of styrofoam.  The most dramatic would be to arrange them to hang in a mobile.  If you want instructions on making a mobile, send an email to samphelps at yahoo.\n\nPlatonic solids are the 3 dimensional shapes where all the sides are the same.  The most familiar is a cube where each side is a square.  Another is the tetrahedron where each side is a triangle.

I think I understand the assignment. You need to build a formula the captures all the possibilities. (i.e wall in front, wall in front and behind, wall in front and to the right, etc)\n\nIt may be quite a little formula! Use help to understand the following formulas: AND, OR, CHOOSE, IF, NOT. Using a combination of nested in IF or CHOOSE statements would work.
