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 268.
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 268 can be written as 268³, which is the exponential form.
Or it can also be written in arithmetic form as, 268 × 268 × 268.
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.
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. 268³ = 268 × 268 × 268
Step 2: You get 19,239,232 as the answer. Hence, the cube of 268 is 19,239,232.
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 268 into two parts. Let a = 260 and b = 8, so a + b = 268
Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³
Step 3: Calculate each term a³ = 260³ 3a²b = 3 × 260² × 8 3ab² = 3 × 260 × 8² b³ = 8³
Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (260 + 8)³ = 260³ + 3 × 260² × 8 + 3 × 260 × 8² + 8³ 268³ = 17,576,000 + 1,612,800 + 499,200 + 512 268³ = 19,239,232
Step 5: Hence, the cube of 268 is 19,239,232.
To find the cube of 268 using a calculator, input the number 268 and use the cube function (if available) or multiply 268 × 268 × 268. This operation calculates the value of 268³, resulting in 19,239,232. It’s a quick way to determine the cube without manual computation.
Step 1: Ensure the calculator is functioning properly.
Step 2: Enter 268
Step 3: If the calculator has a cube function, press it to calculate 268³.
Step 4: If there is no cube function on the calculator, simply multiply 268 three times manually.
Step 5: The calculator will display 19,239,232.
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 268?
The cube of 268 is 19,239,232 and the cube root of 268 is approximately 6.437.
First, let’s find the cube of 268.
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 268³ = 19,239,232
Next, we must find the cube root of 268.
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 ∛268 ≈ 6.437
Hence the cube of 268 is 19,239,232 and the cube root of 268 is approximately 6.437.
If the side length of the cube is 268 cm, what is the volume?
The volume is 19,239,232 cm³.
Use the volume formula for a cube V = Side³.
Substitute 268 for the side length: V = 268³ = 19,239,232 cm³.
How much larger is 268³ than 258³?
268³ – 258³ = 1,973,472.
First, find the cube of 268, that is 19,239,232.
Next, find the cube of 258, which is 17,265,760.
Now, find the difference between them using the subtraction method. 19,239,232 – 17,265,760 = 1,973,472
Therefore, 268³ is 1,973,472 larger than 258³.
If a cube with a side length of 268 cm is compared to a cube with a side length of 18 cm, how much larger is the volume of the larger cube?
The volume of the cube with a side length of 268 cm is 19,239,232 cm³.
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object).
Cubing 268 means multiplying 268 by itself three times: 268 × 268 = 71,824, and then 71,824 × 268 = 19,239,232.
The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube.
Therefore, the volume of the cube is 19,239,232 cm³.
Estimate the cube 267.9 using the cube 268.
The cube of 267.9 is approximately 19,239,232.
First, identify the cube of 268.
The cube of 268 is 268³ = 19,239,232.
Since 267.9 is only a tiny bit less than 268, the cube of 267.9 will be almost the same as the cube of 268.
The cube of 267.9 is approximately 19,239,232 because the difference between 267.9 and 268 is very small.
So, we can approximate the value as 19,239,232.
