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 155.</p>

4 <h2>Cube of 155</h2>

5 <p>A<a>cube</a><a>number</a>is a value obtained by raising a number to the<a>power</a>of 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 multiplied by itself three times results in a negative number. The cube of 155 can be written as \(155^3\), which is the<a>exponential form</a>. Or it can also be written in<a>arithmetic</a>form as \(155 \times 155 \times 155\).</p>

6 <h2>How to Calculate the Value of Cube of 155</h2>

7 <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>(\(a^3\)), 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. - By Multiplication Method - Using a Formula - Using a Calculator</p>

8 <h2>By Multiplication Method</h2>

9 <p>The multiplication method is a process in mathematics used to find the<a>product</a>of 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. Step 1: Write down the cube of the given number. \[ 155^3 = 155 \times 155 \times 155 \] Step 2: You get 3,723,875 as the answer. Hence, the cube of 155 is 3,723,875.</p>

20 <h3>Problem 1</h3>

21 <p>What is the cube and cube root of 155?</p>

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

23 <p>The cube of 155 is 3,723,875 and the cube root of 155 is approximately 5.354.</p>

24 <h3>Explanation</h3>

25 <p>First, let’s find the cube of 155. We know that the cube of a number is such that \(x^3 = y\), where \(x\) is the given number, and \(y\) is the cubed value of that number. So, we get \(155^3 = 3,723,875\). Next, we must find the cube root of 155. We know that the cube root of a number \(x\) is such that \(\sqrt[3]{x} = y\), where \(x\) is the given number, and \(y\) is the cube root value of the number. So, we get \(\sqrt[3]{155} \approx 5.354\). Hence, the cube of 155 is 3,723,875 and the cube root of 155 is approximately 5.354.</p>

26 <p>Well explained 👍</p>

27 <h3>Problem 2</h3>

28 <p>If the side length of a cube is 155 cm, what is the volume?</p>

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

30 <p>The volume is 3,723,875 cm\(^3\).</p>

31 <h3>Explanation</h3>

32 <p>Use the volume formula for a cube \(V = \text{Side}^3\). Substitute 155 for the side length: \(V = 155^3 = 3,723,875 \, \text{cm}^3\).</p>

33 <p>Well explained 👍</p>

34 <h3>Problem 3</h3>

35 <p>How much larger is \(155^3\) than \(150^3\)?</p>

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

37 <p>\(155^3 - 150^3 = 424,875\).</p>

38 <h3>Explanation</h3>

39 <p>First find the cube of \(155^3\), which is 3,723,875. Next, find the cube of \(150^3\), which is 3,375,000. Now, find the difference between them using the subtraction method: 3,723,875 - 3,375,000 = 424,875. Therefore, \(155^3\) is 424,875 larger than \(150^3\).</p>

40 <p>Well explained 👍</p>

41 <h3>Problem 4</h3>

42 <p>If a cube with a side length of 155 cm is compared to a cube with a side length of 5 cm, how much larger is the volume of the larger cube?</p>

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

44 <p>The volume of the cube with a side length of 155 cm is 3,723,875 cm\(^3\).</p>

45 <h3>Explanation</h3>

46 <p>To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object). Cubing 155 means multiplying 155 by itself three times: \(155 \times 155 = 24,025\), and then \(24,025 \times 155 = 3,723,875\). The unit of volume is cubic centimeters (cm\(^3\)) because we are calculating the space inside the cube. Therefore, the volume of the cube is 3,723,875 cm\(^3\).</p>

47 <p>Well explained 👍</p>

48 <h3>Problem 5</h3>

49 <p>Estimate the cube of 154.9 using the cube of 155.</p>

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

51 <p>The cube of 154.9 is approximately 3,723,875.</p>

52 <h3>Explanation</h3>

53 <p>First, identify the cube of 155. The cube of 155 is \(155^3 = 3,723,875\). Since 154.9 is only a tiny bit less than 155, the cube of 154.9 will be almost the same as the cube of 155. The cube of 154.9 is approximately 3,723,875 because the difference between 154.9 and 155 is very small. So, we can approximate the value as 3,723,875.</p>

54 <p>Well explained 👍</p>
