How do I convert 80 pounds to cubic yards?
353215
I work in a hardware store, just as an introduction.  So I am cheating because I know the "rule of thumb" that has all the other factors in it like density and stuff.  Quickcrete (TM) says that an 80lb. bag of premixed concrete will do 2/3 of a cubic foot.  There are 27 cubic feet per cubic yard, so it takes about 40 80lb. bags per cubic yard (at a hardware store they just say "yard" and mean cubic yard).  One bag does one two foot deep fence post, not that anyone asked.

Of course, you would have to convert the English to Metric, but...\n\nObtain the volume (in cubic feet) of the water (i.e. Length times width times height)\nConvert cubic feet to gallons (i.e. 7.48 gallons/cubic foot)\nObtain the weight of the water (i.e. 8.34 pounds/gallon)

to convert from pounds to kg, divide by 2.2\nto convert from kg to pounds, multiply by 2.2\n\n55 kg = 121 pounds\n154 pounds = 70 kg

cubic feet is a measure of volume while kilograms is a measure of weight.\nFirst, you need to find out the density of the material you are tyring to measure. The density will be in either pounds per cubic foot or kilograms per cubic meter.\nIf it's in pounds per cubic foot, multiply the amount of cubic feet (volume) by the density and then you will have pounds. To convert this to Kilograms, divide the number of poudns by 2.2 (rounded).\nIf the density is in kilograms per cubic meter, you can convert the cubic feet to cubic meters. To do so, divide the amount of cubic feet by 35.3 (this is rounded) and then multiply the result by the density.

a cubic foot is 1 x 1 x 1 ... \n\nso you're talking as an equation:\n\n3ft x 2ft x 1/6ft = 6ft^2 x 1/6ft = 1 ft^3\n\nso therefore, the 3 ft. by 2 ft. by 2 in. piece of metal would weigh the same as the 1 cubic ft. of metal!\n\n490 lbs!

That depends on how deep you want the concrete.  Multiply the desired depth (in feet) by 128,000 square feet, then divide by 27 (because there are 27 cubic feet in a cubic yard).

50 yards is the equivalent to 150 feet

First convert every thing so it is in terms of yards...\n\n65 ft * 1 yrd / 3 ft  = 65/3 yards\n\n10 ft * 1 yrd / 3 ft  = 10/3 yards\n\n4 in * (1 ft / 12 in) * (1 yrd / 3 ft) = 4/36 yards\n\nNow multiply to find your volume in yards...\n\n(65/3) * (10/3) * (4/36) = 8.024 yards

first find the area of Mr.brown's lawn by the equation A=lw\nit will be A=25 x 50 = 1250 square feet.\nNow,some fraction 4/500=x/1250 where x is your answer.\ncross multiplication will give you x =10 pounds\nso you need 10 pounds of fertilizer.

First, you need the volume. The formula yields: V = pi rh/3 = 20000pi/3 cubic feet. Since it weighs 50 pounds per cubic foot, the ratio 50 lbs/ft.^3 = 1. So multiplying this to our volume equation, V = 20000pi/3 ft.^3 = 20000pi/3 ft.^3 * 50lbs/ft.^3 = 100000pi/3 lbs. The work function is (25-x)100000pi/3 = W(x). Integrate this result from x=0 to x=25, and you get the answer.

Think of a "foot ruler" (12 inches) - three (3) of those would equal 1 yard (that would be 36 inches or a "yard stick").  So if you are given 65 feet that would equal 21.6666 (or perhaps 21 and 2/3d) yards.  Divide 65 feet by 3 feet.

You can't convert volume (cubic centimeters) to mass (pounds) unless you know a value for density. \n\n5800 cc equals 6.12 US quarts or 12.25 US pints, or 353.9 cubic inches.

Convert the 15' to inches, first note that \n12 inches = 1 foot\n\nmultiply both sides by 15\n\n12 * 15 inches = 15'\n\nok, now how many cubic inches are in 12*15 inches * 4 inches * 2 inches.  Multiply throughout:\n\n12*15*4*2 inches*inches*inches\n\n=\n\n12*15*4*2 inches^3\n\n=\n\n1440 inches^3.\n\nNow how many cubic feet is this?  cube root this idem\n\ncube_root( 1440 ) inches\n\nand since 12 inches = 1 foot, 1 = 1 foot/12 inches so multiplying by 1 foot/12 inches being equivalent to 1 does not chanve value:\n\ncube_root( 1440 ) inches * 1/12 foot\n\nnow cube this:\n\n1440 inches^3 * 1/12^3 foot = 0.83333333333 cubic foot

A cubic metre is 1000 litres.\nA yard is 0.9144 metres, so a cubic yard is (0.9144 x 0.9144 x 0.9144) = 0.764554858 cubic metres.\n\n0.764554858 cubic metres x 1000 = 764.554858 litres.
