How to Find Square Root of 220?
Value of √220 by Long Division Method
Explanation:
- Forming pairs: 02 and 20
- 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 20, to the right of the remainder 1. The new dividend is now 120.
- 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 4) such that 2Z × Z <= 120. After finding Z, together 2 and Z (4) form a new divisor 24 for the new dividend 120.
- Divide 120 by 24 with the quotient as 4, giving the remainder = 120 - 24 × 4 = 120 - 96 = 24.
- Now, let's find the decimal places after the quotient 14.
- 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. 4 + 24 = 28. To the right of 28, find a digit Z (which is 8) such that 28Z × Z <= 2400. Together they form a new divisor (288) for the new dividend (2400).
- Divide 2400 by 288 with the quotient as 8, giving the remainder = 2400 - 288 × 8 = 2400 - 2304 = 96.
- Bring down 00 again. Repeat above steps for finding more decimal places for the square root of 220.
Therefore, the square root of 220 by long division method is 14.8 approx.

Square Root of 220 Solved Examples
-
Example 1: Solve the equation x2 − 220 = 0
Solution:
x2 - 220 = 0 i.e. x2 = 220
x = ±√220
Since the value of the square root of 220 is 14.832,
⇒ x = +√220 or -√220 = 14.832 or -14.832. -
Example 2: If the surface area of a cube is 1320 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 = 1320 in2
⇒ a = ±√220 in
Since length can't be negative,
⇒ a = √220
We know that the square root of 220 is 14.832.
⇒ a = 14.832 in -
Example 3: If the area of an equilateral triangle is 220√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 = 220√3 in2
⇒ a = ±√880 in
Since length can't be negative,
⇒ a = √880 = 2 √220
We know that the square root of 220 is 14.832.
⇒ a = 29.665 in
