How to Find Square Root of 1800?
Value of √1800 by Long Division Method
Explanation:
- Forming pairs: 18 and 00
- Find a number Y (4) such that whose square is <= 18. Now divide 18 by 4 with quotient as 4.
- Bring down the next pair 00, to the right of the remainder 2. The new dividend is now 200.
- Add the last digit of the quotient (4) to the divisor (4) i.e. 4 + 4 = 8. To the right of 8, find a digit Z (which is 2) such that 8Z × Z <= 200. After finding Z, together 8 and Z (2) form a new divisor 82 for the new dividend 200.
- Divide 200 by 82 with the quotient as 2, giving the remainder = 200 - 82 × 2 = 200 - 164 = 36.
- Now, let's find the decimal places after the quotient 42.
- Bring down 00 to the right of this remainder 36. The new dividend is now 3600.
- Add the last digit of quotient to divisor i.e. 2 + 82 = 84. To the right of 84, find a digit Z (which is 4) such that 84Z × Z <= 3600. Together they form a new divisor (844) for the new dividend (3600).
- Divide 3600 by 844 with the quotient as 4, giving the remainder = 3600 - 844 × 4 = 3600 - 3376 = 224.
- Bring down 00 again. Repeat above steps for finding more decimal places for the square root of 1800.
Therefore, the square root of 1800 by long division method is 42.4 approximately.

Square Root of 1800 Solved Examples
-
Example 1: Solve the equation x2 − 1800 = 0
Solution:
x2 - 1800 = 0 i.e. x2 = 1800
x = ±√1800
Since the value of the square root of 1800 is 42.426,
⇒ x = +√1800 or -√1800 = 42.426 or -42.426. -
Example 2: If the surface area of a sphere is 7200π in2. Find the radius of the sphere.
Solution:
Let 'r' be the radius of the sphere.
⇒ Area of the sphere = 4πr2 = 7200π in2
⇒ r = ±√1800 in
Since radius can't be negative,
⇒ r = √1800
The square root of 1800 is 42.426.
⇒ r = 42.426 in -
Example 3: If the area of an equilateral triangle is 1800√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 = 1800√3 in2
⇒ a = ±√7200 in
Since length can't be negative,
⇒ a = √7200 = 2 √1800
We know that the square root of 1800 is 42.426.
⇒ a = 84.853 in
