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 1390.</p>

4 <h2>Cube of 1390</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.</p>

6 <p>When you cube a positive number, the result is always positive.</p>

7 <p>When you cube a<a>negative number</a>, the result is always negative.</p>

8 <p>This is because a negative number by itself three times results in a negative number.</p>

9 <p>The cube of 1390 can be written as 1390³, which is the<a>exponential form</a>.</p>

10 <p>Or it can also be written in<a>arithmetic</a>form as 1390 × 1390 × 1390.</p>

11 <h2>How to Calculate the Value of Cube of 1390</h2>

12 <p>To check whether a number is a cube number or not, we can use the following three methods: the<a>multiplication</a>method, a<a>factor</a><a>formula</a>(a³), or by using a<a>calculator</a>.</p>

13 <p>These three methods will help kids to cube the numbers faster and easier without feeling confused or stuck while evaluating the answers.</p>

15 <h2>By Multiplication Method</h2>

16 <p>The multiplication method is a process in mathematics used to find the<a>product</a>by combining numbers through repeated<a>addition</a>.</p>

17 <p>It is a fundamental operation that forms the basis for more complex mathematical concepts.</p>

18 <p>Step 1: Write down the cube of the given number. 1390³ = 1390 × 1390 × 1390</p>

19 <p>Step 2: You get 2,682,679,000 as the answer. Hence, the cube of 1390 is 2,682,679,000.</p>

45 <h3>Problem 1</h3>

46 <p>What is the cube and cube root of 1390?</p>

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

48 <p>The cube of 1390 is 2,682,679,000 and the cube root of 1390 is approximately 11.086.</p>

49 <h3>Explanation</h3>

50 <p>First, let’s find the cube of 1390. We know that the cube of a number is such that x³ = y</p>

51 <p>Where x is the given number, and y is the cubed value of that number.</p>

52 <p>So, we get 1390³ = 2,682,679,000</p>

53 <p>Next, we must find the cube root of 1390 We know that the cube root of a number ‘x’, such that ∛x = y</p>

54 <p>Where ‘x’ is the given number, and y is the cube root value of the number. So, we get ∛1390 ≈ 11.086</p>

55 <p>Hence the cube of 1390 is 2,682,679,000 and the cube root of 1390 is approximately 11.086.</p>

56 <p>Well explained 👍</p>

57 <h3>Problem 2</h3>

58 <p>If the side length of the cube is 1390 cm, what is the volume?</p>

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

60 <p>The volume is 2,682,679,000 cm³.</p>

61 <h3>Explanation</h3>

62 <p>Use the volume formula for a cube V = Side³. Substitute 1390 for the side length: V = 1390³ = 2,682,679,000 cm³.</p>

63 <p>Well explained 👍</p>

64 <h3>Problem 3</h3>

65 <p>How much larger is 1390³ than 1300³?</p>

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

67 <p>1390³ - 1300³ = 485,679,000.</p>

68 <h3>Explanation</h3>

69 <p>First, find the cube of 1390³, which is 2,682,679,000. Next, find the cube of 1300³, which is 2,197,000,000.</p>

70 <p>Now, find the difference between them using the subtraction method. 2,682,679,000 - 2,197,000,000 = 485,679,000</p>

71 <p>Therefore, 1390³ is 485,679,000 larger than 1300³.</p>

72 <p>Well explained 👍</p>

73 <h3>Problem 4</h3>

74 <p>If a cube with a side length of 1390 cm is compared to a cube with a side length of 90 cm, how much larger is the volume of the larger cube?</p>

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

76 <p>The volume of the cube with a side length of 1390 cm is 2,682,679,000 cm³.</p>

77 <h3>Explanation</h3>

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

79 <p>Cubing 1390 means multiplying 1390 by itself three times: 1390 × 1390 = 1,932,100, and then 1,932,100 × 1390 = 2,682,679,000.</p>

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

81 <p>Therefore, the volume of the cube is 2,682,679,000 cm³.</p>

82 <p>Well explained 👍</p>

83 <h3>Problem 5</h3>

84 <p>Estimate the cube of 1389 using the cube of 1390.</p>

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

86 <p>The cube of 1389 is approximately 2,670,115,269.</p>

87 <h3>Explanation</h3>

88 <p>First, identify the cube of 1390, The cube of 1390 is 1390³ = 2,682,679,000. Since 1389 is only a little less than 1390, the cube of 1389 will be slightly less than the cube of 1390.</p>

89 <p>Using a slight approximation, you find that the cube of 1389 is approximately 2,670,115,269 because the difference between 1389 and 1390 is minor.</p>

90 <p>Well explained 👍</p>
