How to Find Square Root of 345?
Value of √345 by Long Division Method
Explanation:
- Forming pairs: 03 and 45
- 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 45, to the right of the remainder 2. The new dividend is now 245.
- 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 <= 245. After finding Z, together 2 and Z (8) form a new divisor 28 for the new dividend 245.
- Divide 245 by 28 with the quotient as 8, giving the remainder = 245 - 28 × 8 = 245 - 224 = 21.
- Now, let's find the decimal places after the quotient 18.
- Bring down 00 to the right of this remainder 21. The new dividend is now 2100.
- Add the last digit of quotient to divisor i.e. 8 + 28 = 36. To the right of 36, find a digit Z (which is 5) such that 36Z × Z <= 2100. Together they form a new divisor (365) for the new dividend (2100).
- Divide 2100 by 365 with the quotient as 5, giving the remainder = 2100 - 365 × 5 = 2100 - 1825 = 275.
- Bring down 00 again. Repeat above steps for finding more decimal places for the square root of 345.
Therefore, the square root of 345 by long division method is 18.5 approximately.

x2 - 345 = 0 i.e. x2 = 345
x = ±√345
Since the value of the square root of 345 is 18.574,
⇒ x = +√345 or -√345 = 18.574 or -18.574. -
Example 2: If the area of a circle is 345π in2. Find the radius of the circle.
Solution:
Let 'r' be the radius of the circle.
⇒ Area of the circle = πr2 = 345π in2
⇒ r = ±√345 in
Since radius can't be negative,
⇒ r = √345
The square root of 345 is 18.574.
⇒ r = 18.574 in -
Example 3: If the surface area of a cube is 2070 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 = 2070 in2
⇒ a = ±√345 in
Since length can't be negative,
⇒ a = √345
We know that the square root of 345 is 18.574.
⇒ a = 18.574 in
