3 <p>If a number is multiplied by the same number, the result is a square. The inverse of the square is a square root. The square root is used in fields such as vehicle design, finance, etc. Here, we will discuss the square root of 1005.</p>

4 <h2>What is the Square Root of 1005?</h2>

5 <p>The<a>square</a>root is the inverse of the square of the<a>number</a>. 1005 is not a<a>perfect square</a>. The square root of 1005 is expressed in both radical and<a>exponential form</a>. In the radical form, it is expressed as √1005, whereas (1005)(1/2) in the exponential form. √1005 ≈ 31.701, which is an<a>irrational number</a>because it cannot be expressed in the form of p/q, where p and q are<a>integers</a>and q ≠ 0.</p>

6 <h2>Finding the Square Root of 1005</h2>

7 <p>The<a>prime factorization</a>method is used for perfect square numbers. However, the prime factorization method is not used for non-perfect square numbers, where long-<a>division</a>and approximation methods are used. Let us now learn the following methods: -</p>

9 <li>Long division method </li>

10 <li>Approximation method</li>

11 </ol><h2>Square Root of 1005 by Prime Factorization Method</h2>

12 <p>The<a>product</a>of prime<a>factors</a>is the prime factorization of a number. Now let us look at how 1005 is broken down into its prime factors.</p>

13 <p><strong>Step 1:</strong>Finding the prime factors of 1005 Breaking it down, we get 3 x 5 x 67: (31x51 x 671).</p>

14 <p><strong>Step 2:</strong>Now we have found the prime factors of 1005. The second step is to make pairs of those prime factors. Since 1005 is not a perfect square, the digits of the number can’t be grouped in pairs.</p>

15 <p>Therefore, calculating 1005 using prime factorization is not straightforward.</p>

31 <p><strong>Step 2:</strong>Apply the<a>formula</a>: (Given number - smaller perfect square) ÷ (larger perfect square - smaller perfect square) (1005 - 961) ÷ (1024 - 961) = 44 ÷ 63 ≈ 0.698</p>

30 <p><strong>Step 2:</strong>Apply the<a>formula</a>: (Given number - smaller perfect square) ÷ (larger perfect square - smaller perfect square) (1005 - 961) ÷ (1024 - 961) = 44 ÷ 63 ≈ 0.698</p>

32 <p>Adding this to the smaller integer root: 31 + 0.698 = 31.698 So the approximate square root of 1005 is 31.698.</p>

31 <p>Adding this to the smaller integer root: 31 + 0.698 = 31.698 So the approximate square root of 1005 is 31.698.</p>

35 <h3>Problem 1</h3>

36 <p>Can you help Max find the area of a square box if its side length is given as √1050?</p>

37 <p>Okay, lets begin</p>

38 <p>The area of the square is 1050 square units.</p>

39 <h3>Explanation</h3>

40 <p>The area of the square = side².</p>

41 <p>The side length is given as √1050.</p>

42 <p>Area of the square = side² = √1050 × √1050 = 1050.</p>

43 <p>Therefore, the area of the square box is 1050 square units.</p>

44 <p>Well explained 👍</p>

45 <h3>Problem 2</h3>

46 <p>A square-shaped building measuring 1005 square feet is built; if each of the sides is √1005, what will be the square feet of half of the building?</p>

47 <p>Okay, lets begin</p>

48 <p>502.5 square feet</p>

49 <h3>Explanation</h3>

50 <p>We can just divide the given area by 2 as the building is square-shaped.</p>

51 <p>Dividing 1005 by 2 = 502.5.</p>

52 <p>So half of the building measures 502.5 square feet.</p>

53 <p>Well explained 👍</p>

71 <p>Find the perimeter of the rectangle if its length ‘l’ is √1005 units and the width ‘w’ is 40 units.</p>

72 <p>Okay, lets begin</p>

73 <p>The perimeter of the rectangle is approximately 143.402 units.</p>

74 <h3>Explanation</h3>

75 <p>Perimeter of the rectangle = 2 × (length + width).</p>

76 <p>Perimeter = 2 × (√1005 + 40) ≈ 2 × (31.701 + 40) = 2 × 71.701 ≈ 143.402 units.</p>
