Assume smaller pipe fills the tank in x hours and the larger one in (x-2.5) hours. Taking the given inf that both together can fill the tank in 8.4 hours, develop a quadratic equation in x, and solve it. \n\nLarger pipe fills the tank in 15.65 hours whereas the smaller one takes 18.15 hours to fill it.

Let x = length of the corner being cut out.\nThe volume is then\nV = x(12-2x)(8-2x)\nV = x(96 - 24x - 16x + 4x^2)\nV = 4x^3 - 40x^2 + 96x\nTake the derivative of V\nV' = 12x^2 - 80x + 96\nSet equal to 0 and solve for x\n12x^2 - 80x + 96 = 0\n3x^2 - 20x + 24 = 0\nx = (2sqrt(7) + 10)/3\n= 5.097 or 1.569\n12-2(1.569) = 8.861\n8-2(1.569) = 4.861\nThus, the dimensions are\n1.569 by 8.861 by 4.861

Volume = pi * r^2 * h\n\nwhere\nr is the radius\nand\nh is the height\n\nFor example:\nr = 0.9m\nh = 1.2m\nvolume = 3.14159 * 0.9 * 0.9 * 1.2 = 3.0536 cubic metres or 3053.6 litres\n\n_

The first three answers are correct, but confusing. Let me see if I can't simplify this for you. \n\nThe pipe expands in all directions. Assume that the pipe is made of a uniform material, like copper, so we can say that it expands uniformly in all directions.\n\nYou must understand that the metal expands uniformly per unit of measurement. Think of a strip of metal, first. (our piece of tubing cut down the side and unrolled flat.) This means not only that the length, width and thickness expand-- it also means that it will expand so much PER UNIT.\n\nSuppose the copper will expand 1 mm per cm. (We'll use metric, just to keep it simple, because everything will be in tens.) \n\nIf the thickness of the copper strip is 1 cm, \nit will expand to 1.1 cm, or 1 cm plus (1 x 1mm.)\n\nIf the width of the strip is 20 cm, \nit will expand to 22 cm, or 20 cm plus (20 x 1 mm.)\n\nIf the length of the strip is 200 cm, \nit will expand to 220 cm, or 200 cm plus (200 x 1 mm.)\n\nNow, suppose we roll the strip back into a tube again. \n\nThe inner circumference of the tube started out as 20 cm, and the diameter was 20/ pi (which is something less than six cm.)\n\nThe new inner circumference is 22 cm, and the new diameter is 22/pi, which is greater than seven cm. \n\nSo, the metal expands proportionately in all dimensions, and the with of the strip (the circumference of the tube, and thus the diameter) expands MUCH MORE than the thickness of the strip, (which is the same as the tube wall). \n\nIs physics cool, or what?\n\n10 NOV 06, 0419 hrs, GMT.

This is not tricky at all. The volume is 1-1/2 cylinders of "height" 50,000 meters and radius 4 meters.\n\nThe formula for the volume of a cylinder is\n\nV = pi * r^2 * h

volume = 3x2x2 = 12 cubic feet\n\n1 litre = 100 cubic centimetres\n\n30 centremetres = 1 ft\n\nwork the rest out, come you can do it

If the tank is a cylinder, the Volume is πr²h.  If you get the volume in cubic feet, multiply by 7.5 to get gallons.
