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 cubes of 187.

Cube of 187

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 by itself three times results in a negative number.

The cube of 187 can be written as 187³, which is the exponential form. Or it can also be written in arithmetic form as, 187 × 187 × 187.

How to Calculate the Value of Cube of 187

In order to check whether a number is a cube number or not, we can use the following three methods, such as 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. 187³ = 187 × 187 × 187

Step 2: You get 6,545,623 as the answer. Hence, the cube of 187 is 6,545,623.

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 187 into two parts, as 180 and 7.

Let a = 180 and b = 7, so a + b = 187

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

Step 3: Calculate each term

a³ = 180³

3a²b = 3 × 180² × 7

3ab² = 3 × 180 × 7²

b³ = 7³

Step 4: Add all the terms together:

(a + b)³ = a³ + 3a²b + 3ab² + b³ (180 + 7)³

= 180³ + 3 × 180² × 7 + 3 × 180 × 7² + 7³ 187³

= 5,832,000 + 680,400 + 26,460 + 343 187³

= 6,545,623

Step 5: Hence, the cube of 187 is 6,545,623.

Using a Calculator

To find the cube of 187 using a calculator, input the number 187 and use the cube function (if available) or multiply 187 × 187 × 187. This operation calculates the value of 187³, resulting in 6,545,623. 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 8 and 7

Step 3: If the calculator has a cube function, press it to calculate 187³.

Step 4: If there is no cube function on the calculator, simply multiply 187 three times manually.

Step 5: The calculator will display 6,545,623.

Tips and Tricks for the Cube of 187

  • 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 187

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 187?

Okay, lets begin

The cube of 187 is 6,545,623 and the cube root of 187 is approximately 5.736.

Explanation

First, let’s find the cube of 187.

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 187³ = 6,545,623

Next, we must find the cube root of 187 We know that cube root of a number ‘x’, such that ³√x = y

Where ‘x’ is the given number, and y is the cube root value of the number

So, we get ³√187 ≈ 5.736

Hence the cube of 187 is 6,545,623 and the cube root of 187 is approximately 5.736.

Problem 2

If the side length of the cube is 187 cm, what is the volume?

Okay, lets begin

The volume is 6,545,623 cm³.

Explanation

Use the volume formula for a cube V = Side³.

Substitute 187 for the side length: V = 187³ = 6,545,623 cm³.

Problem 3

How much larger is 187³ than 100³?

Okay, lets begin

187³ - 100³ = 5,545,623.

Explanation

First find the cube of 187³, that is 6,545,623

Next, find the cube of 100³, which is 1,000,000

Now, find the difference between them using the subtraction method.

6,545,623 - 1,000,000 = 5,545,623

Therefore, the 187³ is 5,545,623 larger than 100³.

Problem 4

If a cube with a side length of 187 cm is compared to a cube with a side length of 50 cm, how much larger is the volume of the larger cube?

Okay, lets begin

The volume of the cube with a side length of 187 cm is 6,545,623 cm³

Explanation

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

Cubing 187 means multiplying 187 by itself three times:

187 × 187 = 34,969, and then 34,969 × 187 = 6,545,623.

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

Therefore, the volume of the cube is 6,545,623 cm³.

Problem 5

Estimate the cube of 186.9 using the cube of 187.

Okay, lets begin

The cube of 186.9 is approximately 6,545,623.

Explanation

First, identify the cube of 187, The cube of 187 is 187³ = 6,545,623.

Since 186.9 is only a tiny bit less than 187, the cube of 186.9 will be almost the same as the cube of 187.

The cube of 186.9 is approximately 6,545,623 because the difference between 186.9 and 187 is very small.

So, we can approximate the value as 6,545,623.
