How to Find Square Root of 776?
Value of √776 by Long Division Method
Explanation:
- Forming pairs: 07 and 76
- Find a number Y (2) such that whose square is <= 7. Now divide 07 by 2 with quotient as 2.
- Bring down the next pair 76, to the right of the remainder 3. The new dividend is now 376.
- Add the last digit of the quotient (2) to the divisor (2) i.e. 2 + 2 = 4. To the right of 4, find a digit Z (which is 7) such that 4Z × Z <= 376. After finding Z, together 4 and Z (7) form a new divisor 47 for the new dividend 376.
- Divide 376 by 47 with the quotient as 7, giving the remainder = 376 - 47 × 7 = 376 - 329 = 47.
- Now, let's find the decimal places after the quotient 27.
- Bring down 00 to the right of this remainder 47. The new dividend is now 4700.
- Add the last digit of quotient to divisor i.e. 7 + 47 = 54. To the right of 54, find a digit Z (which is 8) such that 54Z × Z <= 4700. Together they form a new divisor (548) for the new dividend (4700).
- Divide 4700 by 548 with the quotient as 8, giving the remainder = 4700 - 548 × 8 = 4700 - 4384 = 316.
- Bring down 00 again. Repeat above steps for finding more decimal places for the square root of 776.
Therefore, the square root of 776 by long division method is 27.8 approx.

Square Root of 776 Solved Examples
-
Example 1: Solve the equation x2 − 776 = 0
Solution:
x2 - 776 = 0 i.e. x2 = 776
x = ±√776
Since the value of the square root of 776 is 27.857,
⇒ x = +√776 or -√776 = 27.857 or -27.857. -
Example 2: If the surface area of a cube is 4656 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 = 4656 in2
⇒ a = ±√776 in
Since length can't be negative,
⇒ a = √776
We know that the square root of 776 is 27.857.
⇒ a = 27.857 in -
Example 3: If the area of an equilateral triangle is 776√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 = 776√3 in2
⇒ a = ±√3104 in
Since length can't be negative,
⇒ a = √3104 = 2 √776
We know that the square root of 776 is 27.857.
⇒ a = 55.714 in
