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 158.

Cube of 158

A cube number is a value obtained by raising a number to the power 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 negative number, the result is always negative. This is because a negative number multiplied by itself three times results in a negative number.

The cube of 158 can be written as 158³, which is the exponential form. Or it can also be written in arithmetic form as, 158 × 158 × 158.

How to Calculate the Value of Cube of 158

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

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

Step 1: Write down the cube of the given number. 158³ = 158 × 158 × 158

Step 2: You get 3,944,632 as the answer. Hence, the cube of 158 is 3,944,632.

Using a Formula (a³)

The formula (a + b)³ is a binomial formula for finding the cube of a number. The formula is expanded as a³ + 3a²b + 3ab² + b³.

Step 1: Split the number 158 into two parts. Let a = 150 and b = 8, so a + b = 158

Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³

Step 3: Calculate each term a³ = 150³ 3a²b = 3 × 150² × 8 3ab² = 3 × 150 × 8² b³ = 8³

Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³

(150 + 8)³ = 150³ + 3 × 150² × 8 + 3 × 150 × 8² + 8³

158³ = 3,375,000 + 540,000 + 28,800 + 512

158³ = 3,944,312

Step 5: Hence, the cube of 158 is 3,944,312.

Using a Calculator

To find the cube of 158 using a calculator, input the number 158 and use the cube function (if available) or multiply 158 × 158 × 158. This operation calculates the value of 158³, resulting in 3,944,632. It’s a quick way to determine the cube without manual computation.

Step 1: Ensure the calculator is functioning properly.

Step 2: Press 1 followed by 5 and 8

Step 3: If the calculator has a cube function, press it to calculate 158³.

Step 4: If there is no cube function on the calculator, simply multiply 158 three times manually.

Step 5: The calculator will display 3,944,632.

Tips and Tricks for the Cube of 158

  • The product of two or more perfect cube numbers is always a perfect cube.
  • A perfect cube can always be expressed as the product of three identical groups of equal prime factors.

Common Mistakes to Avoid When Calculating the Cube of 158

There are some typical errors that kids might make during the process of cubing a number. Let us take a look at five of the major mistakes that kids might make:

Problem 1

What is the cube and cube root of 158?

Okay, lets begin

The cube of 158 is 3,944,632 and the cube root of 158 is approximately 5.390.

Explanation

First, let’s find the cube of 158.

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

So, we get 158³ = 3,944,632

Next, we must find the cube root of 158 We know that the 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

So, we get ∛158 ≈ 5.390

Hence, the cube of 158 is 3,944,632 and the cube root of 158 is approximately 5.390.

Problem 2

If the side length of the cube is 158 cm, what is the volume?

Okay, lets begin

The volume is 3,944,632 cm³.

Explanation

Use the volume formula for a cube V = Side³.

Substitute 158 for the side length: V = 158³ = 3,944,632 cm³.

Problem 3

How much larger is 158³ than 150³?

Okay, lets begin

158³ – 150³ = 569,632.

Explanation

First find the cube of 158, which is 3,944,632.

Next, find the cube of 150, which is 3,375,000.

Now, find the difference between them using the subtraction method. 3,944,632 – 3,375,000 = 569,632

Therefore, 158³ is 569,632 larger than 150³.

Problem 4

If a cube with a side length of 158 cm is compared to a cube with a side length of 8 cm, how much larger is the volume of the larger cube?

Okay, lets begin

The volume of the cube with a side length of 158 cm is 3,944,632 cm³, which is significantly larger than the volume of the 8 cm cube.

Explanation

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

Cubing 158 means multiplying 158 by itself three times: 158 × 158 = 24,964, and then 24,964 × 158 = 3,944,632.

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

Therefore, the volume of the cube is 3,944,632 cm³.

Problem 5

Estimate the cube of 157.9 using the cube of 158.

Okay, lets begin

The cube of 157.9 is approximately 3,944,632.

Explanation

First, identify the cube of 158, The cube of 158 is 158³ = 3,944,632.

Since 157.9 is only a tiny bit less than 158, the cube of 157.9 will be almost the same as the cube of 158.

The cube of 157.9 is approximately 3,944,632 because the difference between 157.9 and 158 is very small.

So, we can approximate the value as 3,944,632.
