To fill a 12x30 above ground pool, you first need to calculate its volume. The formula for the volume of a cylindrical pool is V = πr²h, where r is the radius and h is the height. For a 12-foot diameter pool, the radius is 6 feet, and if the height is 30 inches (2.5 feet), the volume is approximately 282.74 cubic feet. Since there are about 7.48 gallons in a cubic foot, you'll need about 2,112 gallons of water to fill the pool.
To calculate the amount of concrete needed for a 12x30 slab, you first determine the area by multiplying the length (30 feet) by the width (12 feet), which equals 360 square feet. If the slab is to be 4 inches thick, convert the thickness to feet (4 inches = 1/3 feet) and then calculate the volume: 360 square feet x 1/3 feet = 120 cubic feet. Since there are 27 cubic feet in a cubic yard, divide 120 by 27 to find that approximately 4.44 cubic yards of concrete is needed.
To build a 12x30 deck using 2x6 boards, you need to determine the total area of the deck and the coverage of each board. The deck area is 360 square feet (12 feet x 30 feet). A 2x6 board typically covers about 5.5 inches in width (actual size), so you can fit approximately 5.5 boards across the width of the deck (12 feet = 144 inches). With 30 feet length, you would need around 33 boards (30 feet / 1 foot per board) to cover the length, resulting in approximately 165 boards total (33 boards x 5). Therefore, you would need around 165 2x6x12 boards, but it's always wise to account for waste and cuts, so purchasing a few extra is recommended.
A quick search found the number '12' mentioned 48 times (4x12) AND the world 'twelve' mentioned 133 times.The number 12 in bible numerology means 'organizational beginnings' and can be seen in the Hebrew calendar of 360 day/year (12x30), Jacob/Israel's 12 sons beginning the 12 Tribes of Israel, Abraham's son Ishmael having 12 sons to begin the Arab peoples and Jesus having 12 Apostles to begin the Church of God on Earth.
I have a Dolfino Easy-set pool (16 x 42") I was also looking for an easy schedule and came across a chemical kit sold in Canada in Canadian Tire stores. This kit was made for these "inflatable" pools and was relatively inexpensive. On the side it lists start-up schedules and maintenance schedules (how much and how often) for each of the pool sizes. I'd be happy to email anyone with the information on the box. Just let me know the size of your pool. I believe Walmart in the US also sells these kits. I've had wonderful luck with mine. can you use the pump to release the water in the street, when you empty the pool. Our backyard (where the pool is)is lower than the frontyard, whe might need a pump.
SHOCK IT,ADD ALGAECIDE AFTER IT HAS A BALANCE OF 5 CHLORINE LEVEL,....CLEAN THE FILTER REPEATEDLY DAILY,...BRUSH YOUR POOL TWICE A DAY,....CHECK REGULARLY WITH A TEST KIT,....KEEP SWIMMING TO GET YOUR CHEMICALS TO AIRATE AND WORK.....YOU HAVE TO KEEP UP WITH ANY POOL BUT IT SURE IS WORTH IT,HAVE SOMEONE WHO KNOWS POOLS TAKE CARE OF IT WHILE ON VACATION AND LET PEOPLE SWIM IN IT WHILE YOUR GONE TOO,THAT STIRS THINGS UP FOR THE FILTER...G-LUCK! If you want to hurry the process just cast some flocculant onto the surface of the water this will force the algae to the bottom after a couple of days then vacuum the bottom layer of the water to waste. Your pool shop should be able to give you advice on this.RB
The typical sized person needs about 30" width at any table. Using your geometry lessons from school, lets invent a rule you can always use for seating and table sizing. For rectangular and square tables, it should be easy enough. Measure the length of any side (in inches) and divide by 30. If you get a decimal, round down for comfort (round up if an emergency seat is needed). For example, a 6' long rectangular table is 72" in length. 72/30=2.4 (that's 72" divided by 30" per person = 2.4 persons). So, you can fit 2 on each side. I'd only squeeze in another soul if we're seating kids. Round tables are a little trickier but not too hard to figure. Circumference (length around a circle) = Diameter (length across the middle of the circle) x Pi. Pi = 3.1416. If you use 3 instead of Pi, your table will just grow in size slightly. So, back to the 30" per person rule. Seating for 12 means you need 12x30=360 (that's 12 people x 30" per person = 360" circumference needed). Then you just divide by Pi (or 3 to keep it simple) to get the table size in diameter. 360"/3=120" diameter. 120"= 10'-0" You need a 10' diameter table. Luckily, that is a common size. You'll have to purchase or rent tables by their commonly manufactured sizes... and, of course, if you call, they'll probably just tell you how many can sit at each size. Oh well, at least if you're OCD, you can now fine tune and confirm! : )
