The best way to solve this is to break the total volume of the pool up into two simple shapes.

The upper volume of the pool will be a simple rectangular solid with the following dimensions:

L=7m
W=5m
D=1m

Volume of this section = L x W x D = 35 m^3

Now the lower volume of the pool will be a a triangular prism solid with he following dimensions:

Base=7m
Height=2m (3m total - 1m top section)
W=5m

Volume of this section = 0.5 x B x H x W = 35m^3

Now just add these two sections together to find the total volume of the pool:

V1 + V2 = 35 m^3 + 35 m^3 = 70 m^3

Therefore the total volume of the pool is 70 cubic meters.

I hope that was helpful to you, good luck.

### My pool is 16feet wide by 32 long 10 feet deep what is the square footage

What you looking to know?

Square feet suggests a flat area, like the floor plan of the pool, which would be 16 x 32 = 512 square feet. Like you'd measure walls for tiles or paper etc.

As you've given 3 dimensions, sounds like your after the cubic capacity/volume of the pool, in which case your looking at cubic feet (same as flat area above, but with the added depth to go from flat 2d, to 3d (2 vs 3 dimensions)), which would be 16 x 32 x 10 = 5,120 cubic feet.

### My kreepy krauly wont clean the deep end of the swimming pool.

Your situation is unusual in that most of the time these will stay in the deep end and not get to the shallow end. Make sure that your hose is the proper length and the hose weights are in the right positions

Up to 4 feet water, 1 weight at one foot away from Kreepy
4-7 feet water, add a second weight at 6 feet from Kreepy
7-12 feet water add a third weight at 10 feet from Kreepy.

It can take some trial and error to get the Kreepy to cover the whole pool. This includes adding or removing hose sections, and adjusting the pool return "eyeballs" to different directions.

### How much shock n swim for a pool 16 x42

What you appear to be asking is the volume of your Pool in gallons! Here is the formula and resulting answer:

Length X Width X average Depth X 7.5 (for rectangluar) (or 5.9 for a circle or oval)

You need to know 3 values:

The overall length in feet (assuming 42 on your note)
The overall Width in feet (assuming 16 on your note)
The average depth, take a depth measurement at 3-4 locations equally apart along the length from deep to shallow (or vice-versa) (example might 8ft, 6ft, 4ft, 3ft) add these measurements together and then divide the total sum by the number of depth measurements (example 4) this will be the average (example 5.25)

So the resulting formula would read 42 x 16 x 5.25 x 7.5 = 26,460 gallons for the example

Your shock product should clearly state how much one bag will treat a given volume (example 10,000 gals) for regular treatment or shocking. Usually shocking involves doubling or even tripling the normal maintenance dosage, but check the product labels and instructions for manufacturer's recommendation.

### Vac gets stuck in deep end and can't get to shallow end

What type of pool do you have? These specific pool cleaners are made for flat bottomed above ground pools. They are not made to move from deep end to shallow end. If you are using this on an in ground pool that has both shallow and deep or a dished above ground pool, you are not going to get accurate cleaning.

### Won't go in shallow end to clean

If your floats have started to absorb water, the unit may become reluctant to climb the slope from the deep end to the shallow end, although it may still at least start to climb and clean the wall. There are 3 installed floats in the unit bottom plate: 1 "h" float and 2 pocket floats. Aqua Service Distributors in Sequin, TX had a good price on replacements. Good people, too. S.

### NEED TO CHANGE PHOTO RESOLUTION

■ Number of pixels
Select a higher number of pixels for clearer
pictures when printing.
Select a lower number of pixels [ ] (0.3M
EZ) to store more pictures. Fewer pixels also
means it is easier to send pictures by e-mail
or use them on a homepage.
■ When the aspect ratio setting is
[h]
DMC-LS75/DMC-LS70
(7M)
3072 × 2304 pixels
DMC-LS60 only
(6M)
2816 × 2112 pixels
DMC-LS75/DMC-LS70
(5M EZ)
2560 × 1920 pixels
(3M EZ) 2048 × 1536 pixels
(2M EZ) 1600 × 1200 pixels
(1M EZ) 1280 × 960 pixels
(0.3M EZ) 640 × 480 pixels

on the menu I believe the Panasonic calls it aspect ratio
