Cube of 266

Professor Greenline Explaining Math Concepts

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 266.

Cube of 266

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 266 can be written as 266³, which is the exponential form.

 

Or it can also be written in arithmetic form as 266 × 266 × 266.

How to Calculate the Value of Cube of 266

In order 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 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. 266³ = 266 × 266 × 266

 

Step 2: You get 18,848,696 as the answer. Hence, the cube of 266 is 18,848,696.

Professor Greenline from BrightChamps

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 266 into two parts, as 260 and 6. Let a = 260 and b = 6, so a + b = 266

 

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

 

Step 3: Calculate each term a³ = 260³ 3a²b = 3 × 260² × 6 3ab² = 3 × 260 × 6² b³ = 6³

 

Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (260 + 6)³ = 260³ + 3 × 260² × 6 + 3 × 260 × 6² + 6³ 266³ = 17,576,000 + 1,209,600 + 280,800 + 216 266³ = 18,848,616

 

Step 5: Hence, the cube of 266 is 18,848,616.

Using a Calculator

To find the cube of 266 using a calculator, input the number 266 and use the cube function (if available) or multiply 266 × 266 × 266. This operation calculates the value of 266³, resulting in 18,848,696. It’s a quick way to determine the cube without manual computation.

 

Step 1: Ensure the calculator is functioning properly.

 

Step 2: Press 2 followed by 6 and 6

 

Step 3: If the calculator has a cube function, press it to calculate 266³.

 

Step 4: If there is no cube function on the calculator, simply multiply 266 three times manually.

 

Step 5: The calculator will display 18,848,696.

Problem 1

What is the cube and cube root of 266?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The cube of 266 is 18,848,696 and the cube root of 266 is approximately 6.437.

Explanation

First, let’s find the cube of 266.

We know that the 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 266³ = 18,848,696 Next, we must find the cube root of 266

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 ∛266 ≈ 6.437

Hence the cube of 266 is 18,848,696 and the cube root of 266 is approximately 6.437.

Problem 2

If the side length of the cube is 266 cm, what is the volume?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The volume is 18,848,696 cm³.

Explanation

Use the volume formula for a cube V = Side³.

Substitute 266 for the side length: V = 266³ = 18,848,696 cm³.

Problem 3

How much larger is 266³ than 260³?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

266³ – 260³ = 1,272,696.

Explanation

First, find the cube of 266³, that is 18,848,696

Next, find the cube of 260³, which is 17,576,000

Now, find the difference between them using the subtraction method. 18,848,696 – 17,576,000 = 1,272,696

Therefore, 266³ is 1,272,696 larger than 260³.

Problem 4

If a cube with a side length of 266 cm is compared to a cube with a side length of 60 cm, how much larger is the volume of the larger cube?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The volume of the cube with a side length of 266 cm is 18,848,696 cm³

Explanation

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

Cubing 266 means multiplying 266 by itself three times: 266 × 266 = 70,756, and then 70,756 × 266 = 18,848,696.

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

Therefore, the volume of the cube is 18,848,696 cm³.

Problem 5

Estimate the cube of 265.9 using the cube of 266.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The cube of 265.9 is approximately 18,848,696.

Explanation

First, identify the cube of 266,

The cube of 266 is 266³ = 18,848,696.

Since 265.9 is only a tiny bit less than 266, the cube of 265.9 will be almost the same as the cube of 266.

The cube of 265.9 is approximately 18,848,696 because the difference between 265.9 and 266 is very small.

So, we can approximate the value as 18,848,696.
