How to Find Square Root of 480?
Value of √480 by Long Division Method
Explanation:
 Forming pairs: 04 and 80
 Find a number Y (2) such that whose square is <= 4. Now divide 04 by 2 with quotient as 2.
 Bring down the next pair 80, to the right of the remainder 0. The new dividend is now 80.
 Add the last digit of the quotient (2) to the divisor (2) i.e. 2 + 2 = 4. To the right of 4, find a digit Z (which is 1) such that 4Z × Z <= 80. After finding Z, together 4 and Z (1) form a new divisor 41 for the new dividend 80.
 Divide 80 by 41 with the quotient as 1, giving the remainder = 80  41 × 1 = 80  41 = 39.
 Now, let's find the decimal places after the quotient 21.
 Bring down 00 to the right of this remainder 39. The new dividend is now 3900.
 Add the last digit of quotient to divisor i.e. 1 + 41 = 42. To the right of 42, find a digit Z (which is 9) such that 42Z × Z <= 3900. Together they form a new divisor (429) for the new dividend (3900).
 Divide 3900 by 429 with the quotient as 9, giving the remainder = 3900  429 × 9 = 3900  3861 = 39.
 Bring down 00 again. Repeat above steps for finding more decimal places for the square root of 480.
Therefore, the square root of 480 by long division method is 21.9 approximately.

Square Root of 480 Solved Examples

Example 1: Solve the equation x^{2} − 480 = 0
Solution:
x^{2}  480 = 0 i.e. x^{2} = 480
x = ±√480
Since the value of the square root of 480 is 21.909,
⇒ x = +√480 or √480 = 21.909 or 21.909. 
Example 2: If the area of a square is 480 in^{2}. Find the length of the side of the square.
Solution:
Let 'a' be the length of the side of the square.
⇒ Area of the square = a^{2} = 480 in^{2}
⇒ a = ±√480 in
Since length can't be negative,
⇒ a = √480 = 21.909 in 
Example 3: If the surface area of a cube is 2880 in^{2}. 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 = 6a^{2} = 2880 in^{2}
⇒ a = ±√480 in
Since length can't be negative,
⇒ a = √480
We know that the square root of 480 is 21.909.
⇒ a = 21.909 in
FAQs on the Square Root of 480
What is the Value of the Square Root of 480?
The square root of 480 is 21.9089.
Why is the Square Root of 480 an Irrational Number?
Upon prime factorizing 480 i.e. 2^{5} × 3^{1} × 5^{1}, 2 is in odd power. Therefore, the square root of 480 is irrational.
Evaluate 3 plus 15 square root 480
The given expression is 3 + 15 √480. We know that the square root of 480 is 21.909. Therefore, 3 + 15 √480 = 3 + 15 × 21.909 = 3 + 328.634 = 331.634
If the Square Root of 480 is 21.909. Find the Value of the Square Root of 4.8.
Let us represent √4.8 in p/q form i.e. √(480/100) = 4.8/10 = 2.191. Hence, the value of √4.8 = 2.191
What is the Square of the Square Root of 480?
The square of the square root of 480 is the number 480 itself i.e. (√480)^{2} = (480)^{2/2} = 480.
Is the number 480 a Perfect Square?
The prime factorization of 480 = 2^{5} × 3^{1} × 5^{1}. Here, the prime factor 2 is not in the pair. Therefore, 480 is not a perfect square.
