3 <p>A number we multiply by itself three times to get the original number is its cube root. It has various uses in real life, such as finding the volume of cube-shaped objects and designing structures. We will now find the cube root of 287 and explain the methods used.</p>

4 <h2>What is the Cube Root of 287?</h2>

5 <p>We have learned the definition<a>of</a>the<a>cube</a>root. Now, let’s learn how it is represented using a<a>symbol</a>and<a>exponent</a>. The symbol we use to express the cube root is the radical sign (∛), and the exponent we use is ⅓.</p>

6 <p>In<a>exponential form</a>, ∛287 is written as 287^(1/3). The cube root is just the opposite operation of finding the cube of a<a>number</a>. For example: Assume ‘y’ as the cube root of 287, then y^3 can be 287. Since the cube root of 287 is not an exact value, we can write it as approximately 6.646.</p>

7 <h2>Finding the Cube Root of 287</h2>

8 <p>Finding the<a>cube root</a>of a number is to identify the number that must be multiplied three times resulting in the target number. Now, we will go through the different ways to find the cube root of 287. The common methods we follow to find the cube root are given below:</p>

9 <ul><li>Prime factorization method</li>

10 <li>Approximation method</li>

11 <li>Subtraction method</li>

12 <li>Halley’s method</li>

13 </ul><p>To find the cube root of a non-<a>perfect number</a>, we often follow Halley’s method. Since 287 is not a<a>perfect cube</a>, we use Halley’s method.</p>

14 <h2>Cube Root of 287 by Halley’s method</h2>

15 <p>Let's find the cube root of 287 using Halley’s method.</p>

16 <p>The<a>formula</a>is: ∛a ≅ x((x^3 + 2a) / (2x^3 + a))</p>

17 <p>where: a = the number for which the cube root is being calculated</p>

18 <p>x = the nearest perfect cube Substituting,</p>

19 <p>a = 287;</p>

20 <p>x = 6</p>

21 <p>∛a ≅ 6((6^3 + 2 × 287) / (2 × 6^3 + 287))</p>

22 <p>∛287 ≅ 6((216 + 574) / (432 + 287))</p>

23 <p>∛287 ≅ 6.646</p>

24 <p>The cube root of 287 is approximately 6.646.</p>

29 <h3>Problem 1</h3>

30 <p>Imagine you have a cube-shaped toy that has a total volume of 287 cubic centimeters. Find the length of one side of the box equal to its cube root.</p>

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

32 <p>Side of the cube = ∛287 ≈ 6.646 units</p>

33 <h3>Explanation</h3>

34 <p>To find the side of the cube, we need to find the cube root of the given volume.</p>

35 <p>Therefore, the side length of the cube is approximately 6.646 units.</p>

36 <p>Well explained 👍</p>

37 <h3>Problem 2</h3>

38 <p>A company manufactures 287 cubic meters of material. Calculate the amount of material left after using 100 cubic meters.</p>

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

40 <p>The amount of material left is 187 cubic meters.</p>

41 <h3>Explanation</h3>

42 <p>To find the remaining material, we need to subtract the used material from the total amount:</p>

43 <p>287 - 100 = 187 cubic meters.</p>

44 <p>Well explained 👍</p>

45 <h3>Problem 3</h3>

46 <p>A bottle holds 287 cubic meters of volume. Another bottle holds a volume of 50 cubic meters. What would be the total volume if the bottles are combined?</p>

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

48 <p>The total volume of the combined bottles is 337 cubic meters.</p>

49 <h3>Explanation</h3>

50 <p>Let’s add the volume of both bottles:</p>

51 <p>287 + 50 = 337 cubic meters.</p>

52 <p>Well explained 👍</p>

53 <h3>Problem 4</h3>

54 <p>When the cube root of 287 is multiplied by 2, calculate the resultant value. How will this affect the cube of the new value?</p>

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

56 <p>2 × 6.646 ≈ 13.292 The cube of 13.292 ≈ 2345.3</p>

57 <h3>Explanation</h3>

58 <p>When we multiply the cube root of 287 by 2, it results in a significant increase in the volume because the cube increases exponentially.</p>

59 <p>Well explained 👍</p>

60 <h3>Problem 5</h3>

61 <p>Find ∛(100+187).</p>

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

63 <p>∛(100+187) = ∛287 ≈ 6.646</p>

64 <h3>Explanation</h3>

65 <p>As shown in the question ∛(100+187), we can simplify that by adding them.</p>

66 <p>So, 100 + 187 = 287.</p>

67 <p>Then we use this step:</p>

68 <p>∛287 ≈ 6.646 to get the answer.</p>

69 <p>Well explained 👍</p>

70 <h2>FAQs on 287 Cube Root</h2>

71 <h3>1.Can we find the Cube Root of 287?</h3>

72 <p>No, we cannot find the cube root of 287 exactly as the cube root of 287 is not a whole number. It is approximately 6.646.</p>

73 <h3>2.Why is the Cube Root of 287 irrational?</h3>

74 <p>The cube root of 287 is irrational because its<a>decimal</a>value goes on without an end and does not repeat.</p>

75 <h3>3.Is it possible to get the cube root of 287 as an exact number?</h3>

76 <p>No, the cube root of 287 is not an exact number. It is a decimal that is about 6.646.</p>

77 <h3>4.Can we find the cube root of any number using prime factorization?</h3>

78 <p>The prime factorization method can be used to calculate the cube root of perfect cube numbers, but it is not the right method for non-perfect cube numbers. For example, 2 × 2 × 2 = 8, so 8 is a perfect cube.</p>

79 <h3>5.Is there any formula to find the cube root of a number?</h3>

80 <p>Yes, the formula we use for the cube root of any number ‘a’ is a^(1/3).</p>

81 <h2>Important Glossaries for Cube Root of 287</h2>

82 <ul><li><strong>Cube root:</strong>The number that is multiplied three times by itself to get the given number is the cube root of that number. </li>

83 <li><strong>Perfect cube:</strong>A number is a perfect cube when it is the product of multiplying a number three times by itself. A perfect cube always results in a whole number. For example: 2 × 2 × 2 = 8, therefore, 8 is a perfect cube. </li>

84 <li><strong>Exponent:</strong>The exponent form of the number denotes the number of times a number can be multiplied by itself. In 287^(1/3), ⅓ is the exponent that denotes the cube root of 287. </li>

85 <li><strong>Radical sign:</strong>The symbol that is used to represent a root is expressed as (∛).</li>

86 <li><strong>Irrational number:</strong>Numbers that cannot be put in fractional forms are irrational. For example, the cube root of 287 is irrational because its decimal form goes on continuously without repeating the numbers.</li>
