from a 1400 ft. height of sand in a 20hectare space,how many ton of sand can you get?
477134
you can't get any sand from it. because height means distance above the sand. so for 1400ft depth only we can get sand man

Base area x height of water.
981841
area of the base times the height.

About 140 to 160 lbs.

The sizes of the sand grains vary thus their number in one 8 oz cup will vary also. For example, coarse sand granule is between 0.020 and 0.39 in, while very fine sand granule is between 0.0025 and  0.0049 in. I hope my answer was of help to you.

Volume = 1/48 * 1*1 = 1/48 cu ft\ndensity = 480 pounds per cu ft\n\nmass = density*volume = 480* 1/48 lb = 10 lb

I am not sure  how to campos your tons!?

Want to see something neat??\n\nType "19 gallons in cubic feet." into google.\n\nWorks for all kinds of conversions.

Get a shovel and a pail and go to the beach. Pound some sand..into the pail, I mean, and you'll have a great source of it.\n\nOr break a window.

128 cubic feet.  4 * 4 * 8 = 128

How many grains of sand are there on a beach?\n\nSomething like that.
527146
3.14 * 20 * 20 = 1256 sq. mm.

it varies on how large the beach in question is. larger=more sand

Around 1400 Kilometers

If 8, 10 and 4 are all feet, you just need to multiply them to get 320 cubic feet. If they are measured in something else, I suggest you convert them first to feet and then multiply... good luck!

this question doesn't make sense.  or are you looking for the dimensions that could possible give you 2500 sq feet.  in that case, just find 2 numbers that when multiplied give 2500.  some examples:\n\n2x1250\n50x50\n10x250\n.25x10000\n\nthe reason your question doesn't make sense is that you can make one dimension infinitesimally small while the other dimmension gets huge.  to no end.

First off, just take the cube root (or use that x^y button on your calculator and raise the volume in question to the 0.3333333333 power). 1.8x10^6 cu ft would then be about 121 feet on a side.  Now, yourreal question is how big is 27,000 tons (I assume english units, not metric tons since you went to cubic feet).  That will depend on the density of the substance in question.  27,000 tons of water will take up more room than 27,000 tons of iron. The volume you gave gives a density of about 30lbs/cubic foot, which is about 1/2 the density of water.\n\nThis does sound like something hollow, like a boat, or maybe it is wood. That is a big block of wood. You gonna carve yourself an office building or something? A ten story cubic building is about that volume.
