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 the cube of 242.
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 242 can be written as 242³, which is the exponential form.
Or it can also be written in arithmetic form as, 242 × 242 × 242.
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. 242³ = 242 × 242 × 242
Step 2: You get 14,171,368 as the answer.
Hence, the cube of 242 is 14,171,368.
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 242 into two parts, as 240 and 2. Let a = 240 and b = 2, so a + b = 242
Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³
Step 3: Calculate each term a³ = 240³ 3a²b = 3 × 240² × 2 3ab² = 3 × 240 × 2² b³ = 2³
Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (240 + 2)³ = 240³ + 3 × 240² × 2 + 3 × 240 × 2² + 2³ 242³ = 13,824,000 + 345,600 + 2,880 + 8 242³ = 14,171,368
Step 5: Hence, the cube of 242 is 14,171,368.
To find the cube of 242 using a calculator, input the number 242 and use the cube function (if available) or multiply 242 × 242 × 242. This operation calculates the value of 242³, resulting in 14,171,368. 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 4 and 2
Step 3: If the calculator has a cube function, press it to calculate 242³.
Step 4: If there is no cube function on the calculator, simply multiply 242 three times manually.
Step 5: The calculator will display 14,171,368.
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 242?
The cube of 242 is 14,171,368 and the cube root of 242 is approximately 6.288.
First, let’s find the cube of 242.
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 242³ = 14,171,368 Next, we must find the cube root of 242
We know that the 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√242 ≈ 6.288
Hence the cube of 242 is 14,171,368 and the cube root of 242 is approximately 6.288.
If the side length of the cube is 242 cm, what is the volume?
The volume is 14,171,368 cm³.
Use the volume formula for a cube V = Side³.
Substitute 242 for the side length: V = 242³ = 14,171,368 cm³.
How much larger is 242³ than 202³?
242³ – 202³ = 10,585,648.
First, find the cube of 242³, which is 14,171,368
Next, find the cube of 202³, which is 3,585,720
Now, find the difference between them using the subtraction method. 14,171,368 – 3,585,720 = 10,585,648
Therefore, 242³ is 10,585,648 larger than 202³.
If a cube with a side length of 242 cm is compared to a cube with a side length of 42 cm, how much larger is the volume of the larger cube?
The volume of the cube with a side length of 242 cm is 14,171,368 cm³.
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object).
Cubing 242 means multiplying 242 by itself three times: 242 × 242 = 58,564, and then 58,564 × 242 = 14,171,368.
The unit of volume is cubic centimeters (cm³) because we are calculating the space inside the cube.
Therefore, the volume of the cube is 14,171,368 cm³.
Estimate the cube of 241.9 using the cube of 242.
The cube of 241.9 is approximately 14,171,368.
First, identify the cube of 242, The cube of 242 is 242³ = 14,171,368.
Since 241.9 is only a tiny bit less than 242, the cube of 241.9 will be almost the same as the cube of 242.
The cube of 241.9 is approximately 14,171,368 because the difference between 241.9 and 242 is very small.
So, we can approximate the value as 14,171,368.
