3 <p>When a number is multiplied by itself thrice, the resultant number is called the cube of a number. Cubing is used when comparing sizes of objects or things with cubic measurements. In this topic, we shall learn about the cube of 890.</p>

4 <h2>Cube of 890</h2>

5 <p>A<a>cube</a><a>number</a>is a value obtained by raising a number to the<a>power</a><a>of</a>3, or by multiplying the number by itself three times. When you cube a positive number, the result is always positive. When you cube a<a>negative number</a>, the result is always negative. This is because a negative number by itself three times results in a negative number.</p>

6 <p>The cube of 890 can be written as 890³, which is the<a>exponential form</a>. Or it can also be written in<a>arithmetic</a>form as, 890 × 890 × 890.</p>

7 <h2>How to Calculate the Value of Cube of 890</h2>

8 <p>In order to check whether a number is a cube number or not, we can use the following three methods, such as<a>multiplication</a>method, a<a>factor</a><a>formula</a>(a³), or by using a<a>calculator</a>. These three methods will help kids to cube the numbers faster and easier without feeling confused or stuck while evaluating the answers.</p>

12 </ul><h3>By Multiplication Method</h3>

13 <p>The multiplication method is a process in mathematics used to find the<a>product</a>of two numbers or quantities by combining them through repeated<a>addition</a>. It is a fundamental operation that forms the basis for more complex mathematical concepts.</p>

14 <p><strong>Step 1:</strong>Write down the cube of the given number.</p>

15 <p>890³ = 890 × 890 × 890</p>

16 <p><strong>Step 2:</strong>You get 704,969,000 as the answer.</p>

17 <p>Hence, the cube of 890 is 704,969,000.</p>

49 <h3>Problem 1</h3>

50 <p>What is the cube and cube root of 890?</p>

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

52 <p>The cube of 890 is 704,969,000 and the cube root of 890 is approximately 9.545.</p>

53 <h3>Explanation</h3>

54 <p>First, let’s find the cube of 890.</p>

55 <p>We know that cube of a number, such that x³ = y, where x is the given number, and y is the cubed value of that number.</p>

56 <p>So, we get 890³ = 704,969,000</p>

57 <p>Next, we must find the cube root of 890 We know that cube root of a number ‘x’, such that ∛x = y, where x is the given number, and y is the cube root value of the number.</p>

58 <p>So, we get ∛890 ≈ 9.545</p>

59 <p>Hence the cube of 890 is 704,969,000 and the cube root of 890 is approximately 9.545.</p>

60 <p>Well explained 👍</p>

61 <h3>Problem 2</h3>

62 <p>If the side length of the cube is 890 cm, what is the volume?</p>

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

64 <p>The volume is 704,969,000 cm³.</p>

65 <h3>Explanation</h3>

66 <p>Use the volume formula for a cube V = Side³.</p>

67 <p>Substitute 890 for the side length: V = 890³ = 704,969,000 cm³.</p>

68 <p>Well explained 👍</p>

69 <h3>Problem 3</h3>

70 <p>How much larger is 890³ than 800³?</p>

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

72 <p>890³ - 800³ = 192,969,000.</p>

73 <h3>Explanation</h3>

74 <p>First find the cube of 890³, that is 704,969,000</p>

75 <p>Next, find the cube of 800³, which is 512,000,000</p>

76 <p>Now, find the difference between them using the subtraction method.</p>

77 <p>704,969,000 - 512,000,000 = 192,969,000.</p>

78 <p>Therefore, the 890³ is 192,969,000 larger than 800³.</p>

79 <p>Well explained 👍</p>

80 <h3>Problem 4</h3>

81 <p>If a cube with a side length of 890 cm is compared to a cube with a side length of 90 cm, how much larger is the volume of the larger cube?</p>

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

83 <p>The volume of the cube with a side length of 890 cm is 704,969,000 cm³.</p>

84 <h3>Explanation</h3>

85 <p>To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object).</p>

86 <p>Cubing 890 means multiplying 890 by itself three times: 890 × 890 = 792,100, and then 792,100 × 890 = 704,969,000.</p>

87 <p>The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube.</p>

88 <p>Therefore, the volume of the cube is 704,969,000 cm³.</p>

89 <p>Well explained 👍</p>

90 <h3>Problem 5</h3>

91 <p>Estimate the cube 889.9 using the cube 890.</p>

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

93 <p>The cube of 889.9 is approximately 704,969,000.</p>

94 <h3>Explanation</h3>

95 <p>First, identify the cube of 890,</p>

96 <p>The cube of 890 is 890³ = 704,969,000.</p>

97 <p>Since 889.9 is only a tiny bit less than 890, the cube of 889.9 will be almost the same as the cube of 890.</p>

98 <p>The cube of 889.9 is approximately 704,969,000 because the difference between 889.9 and 890 is very small.</p>

99 <p>So, we can approximate the value as 704,969,000.</p>

100 <p>Well explained 👍</p>
