When a number is multiplied by itself thrice, the resultant number is called the cube of a number. Cubing is used while comparing sizes of objects or things with cubic measurements. In this topic, we shall learn about cubes of 986.

Cube of 986

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 986 can be written as 986³, which is the exponential form. Or it can also be written in arithmetic form as, 986 × 986 × 986.

How to Calculate the Value of Cube of 986

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. 986³ = 986 × 986 × 986.

Step 2: You get 958,658,336 as the answer.

Hence, the cube of 986 is 958,658,336.

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 986 into two parts. Let a = 980 and b = 6, so a + b = 986.

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

Step 3: Calculate each term

a³= 980³

3a²b = 3 × 980² × 6

3ab² = 3 × 980 × 6²

b³ = 6³

Step 4: Add all the terms together:

(a + b)³ = a³ + 3a²b + 3ab² + b³

(980 + 6)³ = 980³ + 3 × 980² × 6 + 3 × 980 × 6² + 6³

986³ = 941,192,000 + 172,368 + 34,992 + 216

986³ = 958,658,336

Step 5: Hence, the cube of 986 is 958,658,336.

Using a Calculator

To find the cube of 986 using a calculator, input the number 986 and use the cube function (if available) or multiply 986 × 986 × 986. This operation calculates the value of 986³, resulting in 958,658,336. It’s a quick way to determine the cube without manual computation.

Step 1: Ensure the calculator is functioning properly.

Step 2: Press 9 followed by 8 and 6

Step 3: If the calculator has a cube function, press it to calculate 986³.

Step 4: If there is no cube function on the calculator, simply multiply 986 three times manually.

Step 5: The calculator will display 958,658,336.

Tips and Tricks for the Cube of 986

  • 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 986

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 986?

Okay, lets begin

The cube of 986 is 958,658,336, and the cube root of 986 is approximately 9.958.

Explanation

First, let’s find the cube of 986.

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 986³ = 958,658,336

Next, we must find the cube root of 986.

We know that the cube root of a number ‘x’ is such that ∛x = y Where ‘x’ is the given number, and y is the cube root value of the number.

So, we get ∛986 ≈ 9.958.

Hence, the cube of 986 is 958,658,336 and the cube root of 986 is approximately 9.958.

Problem 2

If the side length of the cube is 986 cm, what is the volume?

Okay, lets begin

The volume is 958,658,336 cm³.

Explanation

Use the volume formula for a cube V = Side³.

Substitute 986 for the side length: V = 986³ = 958,658,336 cm³.

Problem 3

How much larger is 986³ than 980³?

Okay, lets begin

986³ – 980³ = 2,788,336.

Explanation

First, find the cube of 986³, which is 958,658,336

Next, find the cube of 980³, which is 941,192,000

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

958,658,336 – 941,192,000 = 17,466,336

Therefore, 986³ is 17,466,336 larger than 980³.

Problem 4

If a cube with a side length of 986 cm is compared to a cube with a side length of 480 cm, how much larger is the volume of the larger cube?

Okay, lets begin

The volume of the cube with a side length of 986 cm is 958,658,336 cm³.

Explanation

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

Cubing 986 means multiplying 986 by itself three times: 986 × 986 = 972,196, and 972,196 × 986 = 958,658,336.

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

Therefore, the volume of the cube is 958,658,336 cm³.

Problem 5

Estimate the cube of 985 using the cube of 986.

Okay, lets begin

The cube of 985 is approximately 958,658,336.

Explanation

First, identify the cube of 986,

The cube of 986 is 986³ = 958,658,336.

Since 985 is only slightly less than 986, the cube of 985 will be almost the same as the cube of 986.

The cube of 985 is approximately 958,658,336 because the difference between 985 and 986 is very small.

So, we can approximate the value as 958,658,336.
