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 269.
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 269 can be written as 269³, which is the exponential form.
Or it can also be written in arithmetic form as 269 × 269 × 269.
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 to cube the numbers faster and easier without feeling confused or stuck while evaluating the answers.
The multiplication method is a process in mathematics used to find the product of numbers 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. 269³ = 269 × 269 × 269
Step 2: Calculate the product to get approximately 19,433,309. Hence, the cube of 269 is approximately 19,433,309.
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 269 into two parts, as 200 and 69. Let a = 200 and b = 69, so a + b = 269
Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³
Step 3: Calculate each term: a³ = 200³ 3a²b = 3 × 200² × 69 3ab² = 3 × 200 × 69² b³ = 69³
Step 4: Add all the terms together: (200 + 69)³ = 200³ + 3 × 200² × 69 + 3 × 200 × 69² + 69³
Step 5: Hence, the cube of 269 is approximately 19,433,309.
To find the cube of 269 using a calculator, input the number 269 and use the cube function (if available) or multiply 269 × 269 × 269. This operation calculates the value of 269³, resulting in approximately 19,433,309. 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 9.
Step 3: If the calculator has a cube function, press it to calculate 269³.
Step 4: If there is no cube function on the calculator, simply multiply 269 three times manually.
Step 5: The calculator will display approximately 19,433,309.
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:
What is the cube and cube root of 269?
The cube of 269 is approximately 19,433,309 and the cube root of 269 is approximately 6.497.
First, let’s find the cube of 269.
We know that the cube of a number is such that x³ = y, where x is the given number and y is the cubed value of that number.
So, we get 269³ = approximately 19,433,309.
Next, we must find the cube root of 269.
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 ∛269 ≈ 6.497. Hence, the cube of 269 is approximately 19,433,309 and the cube root of 269 is approximately 6.497.
If the side length of the cube is 269 cm, what is the volume?
The volume is approximately 19,433,309 cm³.
Use the volume formula for a cube V = Side³.
Substitute 269 for the side length: V = 269³ ≈ 19,433,309 cm³.
How much larger is 269³ than 200³?
269³ – 200³ = approximately 13,433,309.
First, find the cube of 269, which is approximately 19,433,309.
Next, find the cube of 200, which is 8,000,000.
Now, find the difference between them using the subtraction method. 19,433,309 – 8,000,000 = approximately 13,433,309.
Therefore, 269³ is approximately 13,433,309 larger than 200³.
If a cube with a side length of 269 cm is compared to a cube with a side length of 100 cm, how much larger is the volume of the larger cube?
The volume of the cube with a side length of 269 cm is approximately 19,433,309 cm³.
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object).
Cubing 269 means multiplying 269 by itself three times: 269 × 269 = approximately 72,361, and then 72,361 × 269 = approximately 19,433,309.
The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube.
Therefore, the volume of the cube is approximately 19,433,309 cm³.
Estimate the cube 268.9 using the cube 269.
The cube of 268.9 is approximately 19,433,309.
First, identify the cube of 269,
The cube of 269 is 269³ = approximately 19,433,309.
Since 268.9 is only a tiny bit less than 269, the cube of 268.9 will be almost the same as the cube of 269.
The cube of 268.9 is approximately 19,433,309 because the difference between 268.9 and 269 is very small.
So, we can approximate the value as 19,433,309.
