## How to Find Square Root of 1458?

### Value of √1458 by Long Division Method

Explanation:

• Forming pairs: 14 and 58
• Find a number Y (3) such that whose square is <= 14. Now divide 14 by 3 with quotient as 3.
• Bring down the next pair 58, to the right of the remainder 5. The new dividend is now 558.
• Add the last digit of the quotient (3) to the divisor (3) i.e. 3 + 3 = 6. To the right of 6, find a digit Z (which is 8) such that 6Z × Z <= 558. After finding Z, together 6 and Z (8) form a new divisor 68 for the new dividend 558.
• Divide 558 by 68 with the quotient as 8, giving the remainder = 558 – 68 × 8 = 558 – 544 = 14.
• Now, let’s find the decimal places after the quotient 38.
• Bring down 00 to the right of this remainder 14. The new dividend is now 1400.
• Add the last digit of quotient to divisor i.e. 8 + 68 = 76. To the right of 76, find a digit Z (which is 1) such that 76Z × Z <= 1400. Together they form a new divisor (761) for the new dividend (1400).
• Divide 1400 by 761 with the quotient as 1, giving the remainder = 1400 – 761 × 1 = 1400 – 761 = 639.
• Bring down 00 again. Repeat above steps for finding more decimal places for the square root of 1458.

Therefore, the square root of 1458 by long division method is 38.1 approx.

## Square Root of 1458 Solved Examples

1. Example 1: Solve the equation x2 − 1458 = 0

Solution:

x2 – 1458 = 0 i.e. x2 = 1458

x = ±√1458
Since the value of the square root of 1458 is 38.184,
⇒ x = +√1458 or -√1458 = 38.184 or -38.184.

2. Example 2: If the surface area of a cube is 8748 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 = 8748 in2
⇒ a = ±√1458 in
Since length can’t be negative,
⇒ a = √1458
We know that the square root of 1458 is 38.184.
⇒ a = 38.184 in

3. Example 3: If the area of an equilateral triangle is 1458√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 = 1458√3 in2
⇒ a = ±√5832 in
Since length can’t be negative,
⇒ a = √5832 = 2 √1458
We know that the square root of 1458 is 38.184.
⇒ a = 76.368 in
