How to Find Square Root of 356?
Value of √356 by Long Division Method
Explanation:
- Forming pairs: 03 and 56
- Find a number Y (1) such that whose square is <= 3. Now divide 03 by 1 with quotient as 1.
- Bring down the next pair 56, to the right of the remainder 2. The new dividend is now 256.
- Add the last digit of the quotient (1) to the divisor (1) i.e. 1 + 1 = 2. To the right of 2, find a digit Z (which is 8) such that 2Z × Z <= 256. After finding Z, together 2 and Z (8) form a new divisor 28 for the new dividend 256.
- Divide 256 by 28 with the quotient as 8, giving the remainder = 256 - 28 × 8 = 256 - 224 = 32.
- Now, let's find the decimal places after the quotient 18.
- Bring down 00 to the right of this remainder 32. The new dividend is now 3200.
- Add the last digit of quotient to divisor i.e. 8 + 28 = 36. To the right of 36, find a digit Z (which is 8) such that 36Z × Z <= 3200. Together they form a new divisor (368) for the new dividend (3200).
- Divide 3200 by 368 with the quotient as 8, giving the remainder = 3200 - 368 × 8 = 3200 - 2944 = 256.
- Bring down 00 again. Repeat above steps for finding more decimal places for the square root of 356.
Therefore, the square root of 356 by long division method is 18.8 approximately.

Square Root of 356 Solved Examples
-
Example 1: Solve the equation x2 − 356 = 0
Solution:
x2 - 356 = 0 i.e. x2 = 356
x = ±√356
Since the value of the square root of 356 is 18.868,
⇒ x = +√356 or -√356 = 18.868 or -18.868. -
Example 2: If the area of an equilateral triangle is 356√3 in2. Find the length of one of the sides of the triangle.
Solution:
Let 'a' be the length of one of the sides of the equilateral triangle.
⇒ Area of the equilateral triangle = (√3/4)a2 = 356√3 in2
⇒ a = ±√1424 in
Since length can't be negative,
⇒ a = √1424 = 2 √356
We know that the square root of 356 is 18.868.
⇒ a = 37.736 in -
Example 3: If the area of a circle is 356π in2. Find the radius of the circle.
Solution:
Let 'r' be the radius of the circle.
⇒ Area of the circle = πr2 = 356π in2
⇒ r = ±√356 in
Since radius can't be negative,
⇒ r = √356
The square root of 356 is 18.868.
⇒ r = 18.868 in
