How much water does an 18 feet round and 42 inches deep above ground pool hold?
346689
assuming you are going to fill it to about 4" from the rim, you will use approx. 5455 gallons of water

It's gonna be water wait, no inches!!! exercise, watch the salt in take, exercise. Good luck.

Base area x height of water.

you don't start to run into geothermal heating of the rock and water until a depth of about 1000 feet.  So at about 50 feet the ground water will probably be around 50-60 degree fahreneheit.

most are 4 inches deep. guess someone would have to go diving to find out. it varies

Approximately 20 laps, for a standard high school basketball court measuring 84 by 50 feet.\n\n84 + 84 + 50 + 50 = 268\n5280 / 268 = 19.7015 laps\n\n18.33 laps for an NBA/NCAA court\n22.76 laps for a standard jr. high school court

Depends, what size pool do you have?

Here's a good guess. This is based on a Wal-Mart being built in Jacksonville, FL. I designed the fire sprinkler system there, so I know that the store, which is designed using the Wal-Mart cookie cutter store design technique, is approx. 189,000 sq.ft. It is also typically 27 ft. high as it kinda slopes from front to back. Thus, the volume of this typical Wal-Mart store is 5,103,000 cu.ft. That's the same volume as almost 58 olympic sized swimming pools!

42 US gallons (about 34.97 Imperial gallons or 158.99 L).

not that deep... There really is not that much moisture up there.  I would probably say 1-2 feet

I'm assuming that the 50' and the 18' are the distances across.\n\nA lot depends on the shape of the bottom, but let's assume that it's rounded, and you can treat it as an elliptical solid.  Probably not the case--it's probably going to have a greater volume, because it's got straight sides for a portion of its depth...\n\nANYHOW, assume it's d' deep.  Then the volume is roughly:\n\n2*pi*25*9*d/3\n\nor, for semi-diameters a, b, & c\n\n2*pi*a*b*c/3\n\nNow, if you've got a straight part, say h tall, and the part below the straight part is about d' deep, you can fudge the equation as:\n\npi*25*9*h + 2*pi*25*8*d\n\npi, of course, is 3.14159...\n\nA quick and easy approximation to pi, by the way, is \n\n355/113\n\npi is 3.14159265...\n\n355/113 is 3.1415929...\n\nPretty close, and a whale of a lot better than 22/7

Most lap pools are 25 meters. So one lap, (down and back) is 50 meters. A meter is about 3 feet...

ANSWER:\n\nThe resulting pool is 125 feet deep.  The Niagara Falls have been moving up the Niagara River at a rate of 5 feet a year for the last 12,500 years but that changed when it got to this location, because this section consisted of soft sediment rather than rock.

Well, it all depends on where you live.  Some cities have ordinances that only allow a certain size pool, and some cities won't even let you have a pool.  You might want to check some the the regulations out at  your City Hall. Hope I helped!

56" or 56'?? What's the depth of the pool?

You can do this with some math.  I'm assuming 12 feet is the diameter.  So the radius would be half that, or 6 feet.  2.5 feet (30 inches) is the height.\n\nThe volume of a cylinder is the area of the circle, times the height.\n\nV = pi r^2 h\n\nSo the volume is 3.14159 x 36 x 2.5\nThis is approximately 282.743339 cubic feet.\n\nOne cubic foot holds 7.48051945 US gallons, so you multiply 282.74 x 7.48 to get around 2,115 gallons.\n\nIncidentally, a gallon of water weighs 8.34 lbs, so you are talking about 17,639 lbs or nearly 9 tons of water!!!  Be sure the sides and the base are well constructed.
