It is the same as finding the square root.
The square root of 4,356 is 66 . By far the most popular method nowadays is to use a pocket calculator. There is a straightforward method of extracting square roots with a pencil and paper, but it's too complicated to explain in writing, and takes perhaps 50 times as long as with a $10 calculator.
Multiply the area of the water (in square meters) by the average depth (in meters). Then divide by one thousand to get the volume in liters. For a smaller puddle, multiply the area in square centimeters by the average depth in centimeters; then multiply by one thousand.
By using the quadratic equation formula
Generalized Least Square Method also called Least Cubic Method

You can divide the square from a point halfway between two of the corners to a similar point on the opposite side, to produce to rectangles. You can do this vertically or horizontally, but the result is the same. The second method is to divide the square from one corner to the corner directly opposite to it, in effect dividing the square into two triangles.
To approximate the square root of any non perfect square number, you can perform a series of steps: # Guess # Divide # Average For example, let's use the number 20. # Guess - the square root of 20 is around 4. # Divide - 20 / 4 = 5 # Average - The average of 4 (our guess) and 5 (our quotient) is 4.5 # Now divide 20 by 4.5 = about 4.44 # Average 4.44 (our quotient) and 4.5 (our last average) = 4.472 # Repeat as many times as necessary to achieve a sufficient approximation.
I believe you are referring to the technique of estimating a square root by division. Step one: Find the nearest perfect square. 16 in this case. step 2: Divide the number (15.625) by 4 (the square root of 16). The result is about 3.906 Step 3: Take the average of 4 and 3.906, which is 3.953. This is an approximation of the square root of 15.625.
Type in the number and press the square root button which looks like this: √ Alternately, you can type in X1/2 and you'll get the same thing. If you only have a four-function calculator, there are a couple of methods. One is simply trial-and-error: make a guess, square it (multiply it by itself), see if it is too large or too small and adjust your guess. It's accurate, but takes several iterations. Another technique is called the "Babylonian Method". It is similar, but it converges on an answer more quickly. You make a guess, divide the number (that you want to find the square root of) by your guess, and then take the average of that result and your guess. That becomes your next guess. For example, if you want to find the square root of 60, you know that 8x8 is 64 so that's a good starting guess: guess: 8.00000, divide: 60/8.00000 = 7.50000, average = 7.75000 guess: 7.75000, divide: 60/7.75000 = 7.74194, average = 7.74597 guess: 7.74597, divide: 60/7.74597 = 7.74597, (same as the guess, to five places) It's very easy if your calculator has a memory register where you can store the guess. All you have to do is divide and average, divide and average...
This works for me. I am working with 12ft. width rolls. I divide the square yards by 1.333333. If you have 4ft. width rolls, you divide by 0.444444, 6ft. width you divide by 0.666666. Therefore, in this method you need to know at least one other dimension.

No. You can only divide a square into 4, 9, 16 etc (i.e. they must be square numbers.
