A gallon of paint covers 600 sq ft @ 1 mil thickness.  How many sq ft will it cover @ 3 mil thick?

Hi Kid,\nNone, of course. You've already used it up on the 600 sq ft.\nOK. I'll stop being silly.\nHow about 200 sq ft?\nBest regards, \nDave.

3/4-1/8=5/8\n15 gallon=5/8 th part of the gasoline tnk\nTherefore capacity of the gasoline tank is 15X8/5=24 gallon.After filling 3/4 th part of the tank it is still 1-3/4=1/4 part empty\nTherefore it requires 24X1/4 or 6 gallons more to fill the tank.

Well here's some extra info you need to solve the problem:\n\n1 cubic inch = 0.00432900431 US gallons\n\nSo one can has a volume of:\n\nV=(pi)(5)(3/2)^2=35.34291 cubic inches\n\nThey filled 86400 cans which has a volume of:\n\nVtotal = V*86400 = 35.34291*86400 = 3053627.424 cubic inches\n\nThen you need to convert this to gallons so:\n\nVgallons = 0.00432900431 * 3053627.424 = 13219.1662 Gallons

Depends on the height.\n\nV=pi*r^2*h\n\n1 ft^3 = 7.48 gallons (U.S.)

A rectangular prism is simply made up of 6 rectangles.  One pair of rectangles would be 3cm x 3cm (the ends).  The other 4 rectangles would be 3cm x 20cm.  So the total surface area would be the sum.\n\n3cm x 3cm = 9 sq. cm\n3cm x 20cm = 60 sq. cm\n\nSo 9 + 9 + 60 + 60 + 60 + 60 = 258 sq. cm.\n\nIn this case two of the dimensions were the same, but if the sides were h,w,l the total surface area would be:\n= hw + hw + hl + hl + lw + lw\n= 2hw + 2hl + 2lw\n= 2 (hw + hl + lw)\n\nIn your example:\n= 2 (3x3 + 3x20 + 3x20)\n= 2 (129)\n= 258 sq. cm.   (Don't forget the units are sq. cm)

Get the dimensions of the rectangular tank into the same units, then get the volume. the unit could be in^3, cm^3, m^3, ft^3, mi^3, mm^3, km^3, etc. Have them be converted to cm^3 using the ff. conversion units:\n\n1 mi = 5280 ft\n1 ft = 12 in\n1 in = 2.54 cm\n1 m = 10 dm = 100 cm = 1000mm = .1 dam = .01 hm = .001 km\n\nNow, 1 cm^3 = 1 mL. Have it converted into liters using 1000 mL = 1 L. To get gallons, use the ff. conversion unit:\n3.8 L = 1 gal\n\nHope this helps ^_^

Multiply cubic feet by 7.481 to get gallons.

the smaller tank is 900L and the bigger tank is 1200L\n\nTank 1 = T\nTank 2 = T+300\n\n(2/3) T = (1/2) (T+300)\n(2/3) T = (1/2) T + 150\n(4/6) T = (3/6) T + 150\n(1/6) T = 150\nT = 900

that way you can remember the formula with generic terms like L and W then later insert the corresponding numbers.\n\nlength times width equals area\nL * W = A\nl2" * 12" = 144 square inches

Deriving this is one of my favorite derivations.  I only will use exact legal values.\n\n500 mL = how many english fluid ounces.  We'll start with the gallon, 128 fluid ounces.\n\nLegally, there are 231 cubic inches per gallon.\n\n1 gal = 231 in^3\n\nNow take the cube root of both sides, remembering the law of exponents, (a*b)^c = a^c * b^c. A cube root is an exponent of (1/3). Dimensional analysis is the theory that you can manipulate the [gal] and the [in] like they were algebraic unknowns.\n\n1 cube_root_gallon = cube_root(231) * inches ` ` ` ` ` (1)\n\nNow a cube root of a gallon is the length of a side of a cube with volume one gallon. Lets convert this inches to centimeters. Legally\n\n` ` 2.54 cm = 1 inch\n\nmultiply this equation by 1/inch both sides to get\n\n` ` 2.54 cm/inch = inch/inch\n\nnotice that the right side is equivalent to 1\n\n` ` 2.54 cm/inch = 1\n\nNot multiply this equivalent to 1 on the right hand side of equation (1) to get\n\n1 cube_root_gallon = cube_root(231) * inches * 2.54 cm/inch\n\nand cancel the "inch" dimension on the numerator and demonenator right hand side\n\n1 cube_root_gallon = cube_root(231) * 2.54 cm\n\nnow cube both sides to get gallons again, remembering the law of exponents, that is each factor on the right is cubed as well\n\n\n1 gallon = 231 * (2.54)^3 cm^3\n\nNow working on the left hand side, 4 quarts = 1 gallon, so by a similar argument 1 = 4 quarts/gallon and multiplying this to the left hand side of the equation (since multiplying by 1 doesn't change the value)\n\n1 gallon*4 quarts/gallon = 231 * (2.54)^3 cm^3\n\ncancelling "gallon"\n\n4 quarts = 231 * (2.54)^3 cm^3\n\nand 2 pints = 1 quart, so 2 pints/quart = 1, multiplying and cancelling\n\n4 * 2 pints = 231 * (2.54)^3 cm^3\n\nand a pint is legally 16 fluid ounces, 1 pint = 16 fluid oz, thus 1 = 16 fluid oz / pint; multiplying this value of 1 on the left hand side won't change anything, then cancelling "pints"\n\n4 * 2 * 16 fluid oz = 231 * (2.54)^3 cm^3\n\nnow multiply both sides by 500/(231 * (2.54)^3)\n\n4 * 2 * 16 * 500 / (231 * 2.54^3 ) fluid oz = 500 cm^3\n\nsince 1 mL is exactly equivalent to 1 cm^3, our answer is on the left-hand-side.  via good calculator\n\n500 mL = 16.907011350921498584313594983 fluid oz.

We really should go metric. It's all so confusing. Anyway, there are 4 quarts in a gallon, so 11x4=44

Google calculator will give you the answer right away.\n\nJust type "sq ft in an acre" and you'll get back the answer of 43,560 sq. ft.\n\nOr if you want it in sq inches, type "sq inches in an acre" (6,272,640 sq inches).

Volume = area x height\n\n3 inches = 0.25 foot\n\nArea = Pi x d'2 /4 = 3.1416 x 0.25 x 0.25 / 4\nArea = 0.0049\n\nVolume = Area x height\nVolume = 0.0049 x 10 = 0.4908 cubic feet\n \n1 cubic feet = 7.48 gallons  \n\nVolume in gallons = 0.4908 x 7.48 = 3.67 gallons

I take it that's 87.3 square miles...\n\nThere are 63,360 inches in a mile, so in a square mile there are 63360² = 4014489600 square inches in a square mile.\n\nWith 0.79 inches of rain over the area of 87.3 sq miles, and there being 231 square inches in a mile, thats:\n\n87.3 * 0.79 * (big number above) / 231 = 1198559759 gallons\n\n= 11.99x10^8 gallons.
