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 68921 and explain the methods used.</p>

4 <h2>What is the Cube Root of 68921?</h2>

5 <p>We have learned the definition of 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>, ∛68921 is written as 68921(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 68921, then y3 can be 68921. Since the cube root of 68921 is not an immediately obvious value, we can calculate it to find it is exactly 41.</p>

7 <h2>Finding the Cube Root of 68921</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 68921. 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 large number, we often follow the<a>prime factorization</a>method. Since 68921 is a<a>perfect cube</a>, we use this method.</p>

14 <h3>Cube Root of 68921 by Prime Factorization Method</h3>

15 <p>Let's find the cube root of 68921 using the prime factorization method:</p>

16 <p>First, we need to break down the number into its prime<a>factors</a>.</p>

17 <p>68921 = 41 × 41 × 41</p>

18 <p>Since we have three 41s, the cube root is simply one of these factors.</p>

19 <p>So, ∛68921 = 41.</p>

20 <p><strong>The cube root of 68921 is exactly 41.</strong></p>

25 <h3>Problem 1</h3>

26 <p>Imagine you have a cube-shaped toy that has a total volume of 68921 cubic centimeters. Find the length of one side of the cube.</p>

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

28 <p>Side of the cube = ∛68921 = 41 units</p>

29 <h3>Explanation</h3>

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

31 <p>Therefore, the side length of the cube is exactly 41 units.</p>

32 <p>Well explained 👍</p>

33 <h3>Problem 2</h3>

34 <p>A company manufactures 68921 cubic meters of material. Calculate the amount of material left after using 421 cubic meters.</p>

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

36 <p>The amount of material left is 68500 cubic meters.</p>

37 <h3>Explanation</h3>

38 <p>To find the remaining material, subtract the used material from the total amount:</p>

39 <p>68921 - 421 = 68500 cubic meters.</p>

40 <p>Well explained 👍</p>

41 <h3>Problem 3</h3>

42 <p>A bottle holds 68921 cubic meters of volume. Another bottle holds a volume of 8 cubic meters. What would be the total volume if the bottles are combined?</p>

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

44 <p>The total volume of the combined bottles is 68929 cubic meters.</p>

45 <h3>Explanation</h3>

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

47 <p>68921 + 8 = 68929 cubic meters.</p>

48 <p>Well explained 👍</p>

49 <h3>Problem 4</h3>

50 <p>When the cube root of 68921 is multiplied by 2, calculate the resultant value. How will this affect the cube of the new value?</p>

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

52 <p>2 × 41 = 82 The cube of 82 = 551368</p>

53 <h3>Explanation</h3>

54 <p>When we multiply the cube root of 68921 by 2, it results in a significant increase in the volume because the cube increases exponentially.</p>

55 <p>Well explained 👍</p>

56 <h3>Problem 5</h3>

57 <p>Find ∛(46000 + 22921).</p>

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

59 <p>∛(46000 + 22921) = ∛68921 = 41</p>

60 <h3>Explanation</h3>

61 <p>As shown in the question ∛(46000 + 22921), we can simplify that by adding them.</p>

62 <p>So, 46000 + 22921 = 68921.</p>

63 <p>Then we use this step: ∛68921 = 41 to get the answer.</p>
