# How thick does a brick wall need to be if it is too hold 3 feet of water when the whole pond depth is 6 feet?

Doesn't matter what the whole depth is. You mean three feet
above ground? Doesn't matter how thick the wall is either. Depends
on how it is constructed. Why use bricks anyway? You are still
going to have to line it. Look at some books on pond
construction.

### A fountain is of length 144cms ten width of 288 cms and depth of 91 cms so how much liters of water ll be there in 46 cms of depth in the same fountain?

If the fountain is rectangular, measuring (144 cm) x (288 cm),
and holds water to a depth of (46 cm),
then the volume of water is
(144 x 288 x 46) = 1,907,712 cm3 = 1,907.712
liters
It doesn't matter how deep the whole structure is, only how deep
the water is.
The only significance of the "91 cm" dimension is that it defines
the flood stage.

### How much water is in a 18 foot by 36 foot pool?

That all depends on the depth, and if it is deeper on one end.
Sorry, you need more information to answer this correctly.
Do the math yourself when you find out how deep it is, start off
with 18 * 36 * x ("x" being the depth.)
If the pool were to be 5ft deep throughout the whole pool
exactly it would be 3240 Square feet of water. As for gallons, You
would need to convert that number.

### How many gallons of water in a pool 35X90 that is 3 ft deep?

Answer
1000 gallons is way off. The formula for acquiring the number of
gallons a pool contains is the following: 1) Multiply the length x
width (in this case 35w x 90length = 3150 square foot. 2) Figure
out the average depth by adding the deep end and the shallow end
together (ex. what is the depth in the shallowest end and what is
the depth in the deepest end). If it is a rectangle pool it's easy
to figure (in this case you gave the depth at 3 ft., I will assume
that is 3 ft. all the way around) 3) After adding the deep end with
the shallow end divide by two. This gives you the "average" depth
of the pool as a whole (once again, in this case the only number
you've given is 3. If the whole pool is 3 ft. deep then the average
depth is 3 ft. deep) 4) Now, multiply the square footage with the
average depth (in this case, 3150 x 3 = 9450. 5) You then multiply
that number by the constant of 7.5 (in this case 9450 x 7.5 give
you 70,875 gallons of water)
Your answer to how many gallons of water are in a 35 x 90 foot
pool is 70,875.
