How to Find Square Root of 1256?

Square Root of 1256 by Long Division Method

Value of √1256 by Long Division Method

Explanation:

Forming pairs: 12 and 56
Find a number Y (3) such that whose square is <= 12. Now divide 12 by 3 with quotient as 3.
Bring down the next pair 56, to the right of the remainder 3. The new dividend is now 356.
Add the last digit of the quotient (3) to the divisor (3) i.e. 3 + 3 = 6. To the right of 6, find a digit Z (which is 5) such that 6Z × Z <= 356. After finding Z, together 6 and Z (5) form a new divisor 65 for the new dividend 356.
Divide 356 by 65 with the quotient as 5, giving the remainder = 356 - 65 × 5 = 356 - 325 = 31.
Now, let's find the decimal places after the quotient 35.
Bring down 00 to the right of this remainder 31. The new dividend is now 3100.
Add the last digit of quotient to divisor i.e. 5 + 65 = 70. To the right of 70, find a digit Z (which is 4) such that 70Z × Z <= 3100. Together they form a new divisor (704) for the new dividend (3100).
Divide 3100 by 704 with the quotient as 4, giving the remainder = 3100 - 704 × 4 = 3100 - 2816 = 284.
Bring down 00 again. Repeat above steps for finding more decimal places for the square root of 1256.

Therefore, the square root of 1256 by long division method is 35.4 approximately.

Square Root of 1256 Solved Examples

Example 1: Solve the equation x² − 1256 = 0

Solution:

x² - 1256 = 0 i.e. x² = 1256
x = ±√1256
Since the value of the square root of 1256 is 35.440,
⇒ x = +√1256 or -√1256 = 35.440 or -35.440.
Example 2: If the area of a square is 1256 in². Find the length of the side of the square.

Solution:

Let 'a' be the length of the side of the square.
⇒ Area of the square = a² = 1256 in²
⇒ a = ±√1256 in
Since length can't be negative,
⇒ a = √1256 = 35.440 in
Example 3: If the surface area of a cube is 7536 in². Find the length of the side of the cube.

Solution:

Let 'a' be the length of the side of the cube.
⇒ Area of the cube = 6a² = 7536 in²
⇒ a = ±√1256 in
Since length can't be negative,
⇒ a = √1256
We know that the square root of 1256 is 35.440.
⇒ a = 35.440 in
