How to Find Square Root of 280?
Value of √280 by Long Division Method
Explanation:
 Forming pairs: 02 and 80
 Find a number Y (1) such that whose square is <= 2. Now divide 02 by 1 with quotient as 1.
 Bring down the next pair 80, to the right of the remainder 1. The new dividend is now 180.
 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 6) such that 2Z × Z <= 180. After finding Z, together 2 and Z (6) form a new divisor 26 for the new dividend 180.
 Divide 180 by 26 with the quotient as 6, giving the remainder = 180  26 × 6 = 180  156 = 24.
 Now, let's find the decimal places after the quotient 16.
 Bring down 00 to the right of this remainder 24. The new dividend is now 2400.
 Add the last digit of quotient to divisor i.e. 6 + 26 = 32. To the right of 32, find a digit Z (which is 7) such that 32Z × Z <= 2400. Together they form a new divisor (327) for the new dividend (2400).
 Divide 2400 by 327 with the quotient as 7, giving the remainder = 2400  327 × 7 = 2400  2289 = 111.
 Bring down 00 again. Repeat above steps for finding more decimal places for the square root of 280.
Therefore, the square root of 280 by long division method is 16.7 approximately.

Square Root of 280 Solved Examples

Example 1: Solve the equation x^{2} − 280 = 0
Solution:
x^{2}  280 = 0 i.e. x^{2} = 280
x = ±√280
Since the value of the square root of 280 is 16.733,
⇒ x = +√280 or √280 = 16.733 or 16.733. 
Example 2: If the area of a square is 280 in^{2}. 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 = a^{2} = 280 in^{2}
⇒ a = ±√280 in
Since length can't be negative,
⇒ a = √280 = 16.733 in 
Example 3: If the surface area of a cube is 1680 in^{2}. 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 = 6a^{2} = 1680 in^{2}
⇒ a = ±√280 in
Since length can't be negative,
⇒ a = √280
We know that the square root of 280 is 16.733.
⇒ a = 16.733 in
