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 382.
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 382 can be written as 382³, which is the exponential form.
Or it can also be written in arithmetic form as, 382 × 382 × 382.
In order to check whether a number is a cube number or not, we can use the following three methods, such as the 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. 382³ = 382 × 382 × 382
Step 2: You get 55,755,368 as the answer. Hence, the cube of 382 is 55,755,368.
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 382 into two parts, as 380 and 2. Let a = 380 and b = 2, so a + b = 382
Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³
Step 3: Calculate each term a³ = 380³ 3a²b = 3 × 380² × 2 3ab² = 3 × 380 × 2² b³ = 2³
Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (380 + 2)³ = 380³ + 3 × 380² × 2 + 3 × 380 × 2² + 2³ 382³ = 54,872,000 + 867,600 + 4,560 + 8 382³ = 55,744,168
Step 5: Hence, the cube of 382 is 55,755,368.
To find the cube of 382 using a calculator, input the number 382 and use the cube function (if available) or multiply 382 × 382 × 382. This operation calculates the value of 382³, resulting in 55,755,368. It’s a quick way to determine the cube without manual computation.
Step 1: Ensure the calculator is functioning properly.
Step 2: Press 3 followed by 8 and 2
Step 3: If the calculator has a cube function, press it to calculate 382³.
Step 4: If there is no cube function on the calculator, simply multiply 382 three times manually.
Step 5: The calculator will display 55,755,368.
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 382?
The cube of 382 is 55,755,368 and the cube root of 382 is approximately 7.257.
First, let’s find the cube of 382.
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 382³ = 55,755,368
Next, we must find the cube root of 382.
We know that the cube root of a number ‘x’, such that √³x = y
Where ‘x’ is the given number, and y is the cube root value of the number
So, we get √³382 = 7.257
Hence the cube of 382 is 55,755,368 and the cube root of 382 is approximately 7.257.
If the side length of the cube is 382 cm, what is the volume?
The volume is 55,755,368 cm³.
Use the volume formula for a cube V = Side³.
Substitute 382 for the side length: V = 382³ = 55,755,368 cm³.
How much larger is 382³ than 380³?
382³ – 380³ = 867,608.
First, find the cube of 382, that is 55,755,368
Next, find the cube of 380, which is 54,872,000
Now, find the difference between them using the subtraction method. 55,755,368 – 54,872,000 = 883,368
Therefore, 382³ is 883,368 larger than 380³.
If a cube with a side length of 382 cm is compared to a cube with a side length of 10 cm, how much larger is the volume of the larger cube?
The volume of the cube with a side length of 382 cm is 55,755,368 cm³ larger.
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object).
Cubing 382 means multiplying 382 by itself three times: 382 × 382 = 145,924, and then 145,924 × 382 = 55,755,368.
The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube.
Therefore, the volume of the cube is 55,755,368 cm³.
Estimate the cube of 381.9 using the cube of 382.
The cube of 381.9 is approximately 55,755,368.
First, identify the cube of 382,
The cube of 382 is 382³ = 55,755,368.
Since 381.9 is only a tiny bit less than 382, the cube of 381.9 will be almost the same as the cube of 382.
The cube of 381.9 is approximately 55,755,368 because the difference between 381.9 and 382 is very small.
So, we can approximate the value as 55,755,368.
