How to Find Square Root of 154?
Value of √154 by Long Division Method
Explanation:
- Forming pairs: 01 and 54
- Find a number Y (1) such that whose square is <= 1. Now divide 01 by 1 with quotient as 1.
- Bring down the next pair 54, to the right of the remainder 0. The new dividend is now 54.
- 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 2) such that 2Z × Z <= 54. After finding Z, together 2 and Z (2) form a new divisor 22 for the new dividend 54.
- Divide 54 by 22 with the quotient as 2, giving the remainder = 54 - 22 × 2 = 54 - 44 = 10.
- Now, let's find the decimal places after the quotient 12.
- Bring down 00 to the right of this remainder 10. The new dividend is now 1000.
- Add the last digit of quotient to divisor i.e. 2 + 22 = 24. To the right of 24, find a digit Z (which is 4) such that 24Z × Z <= 1000. Together they form a new divisor (244) for the new dividend (1000).
- Divide 1000 by 244 with the quotient as 4, giving the remainder = 1000 - 244 × 4 = 1000 - 976 = 24.
- Bring down 00 again. Repeat above steps for finding more decimal places for the square root of 154.
Therefore, the square root of 154 by long division method is 12.4 approximately.

Square Root of 154 Solved Examples
-
Example 1: Solve the equation x2 − 154 = 0
Solution:
x2 - 154 = 0 i.e. x2 = 154
x = ±√154
Since the value of the square root of 154 is 12.410,
⇒ x = +√154 or -√154 = 12.410 or -12.410. -
Example 2: If the surface area of a cube is 924 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 = 924 in2
⇒ a = ±√154 in
Since length can't be negative,
⇒ a = √154
We know that the square root of 154 is 12.410.
⇒ a = 12.410 in -
Example 3: If the surface area of a sphere is 616π in2. Find the radius of the sphere.
Solution:
Let 'r' be the radius of the sphere.
⇒ Area of the sphere = 4πr2 = 616π in2
⇒ r = ±√154 in
Since radius can't be negative,
⇒ r = √154
The square root of 154 is 12.410.
