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 1378.
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 1378 can be written as 1378³, which is the exponential form.
Or it can also be written in arithmetic form as 1378 × 1378 × 1378.
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 students to cube the numbers faster and easier without feeling confused or stuck while evaluating the answers.
By Multiplication Method Using a Formula Using a Calculator
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. 1378³ = 1378 × 1378 × 1378
Step 2: You get 2,616,683,352 as the answer. Hence, the cube of 1378 is 2,616,683,352.
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 1378 into two parts, as 1300 and 78. Let a = 1300 and b = 78, so a + b = 1378
Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³
Step 3: Calculate each term a³ = 1300³ 3a²b = 3 × 1300² × 78 3ab² = 3 × 1300 × 78² b³ = 78³
Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (1300 + 78)³ = 1300³ + 3 × 1300² × 78 + 3 × 1300 × 78² + 78³ 1378³ = 2,197,000,000 + 394,920,000 + 29,563,200 + 474,152 1378³ = 2,616,683,352
Step 5: Hence, the cube of 1378 is 2,616,683,352.
To find the cube of 1378 using a calculator, input the number 1378 and use the cube function (if available) or multiply 1378 × 1378 × 1378.
This operation calculates the value of 1378³, resulting in 2,616,683,352. It’s a quick way to determine the cube without manual computation.
Step 1: Ensure the calculator is functioning properly.
Step 2: Press 1 followed by 3, 7, and 8.
Step 3: If the calculator has a cube function, press it to calculate 1378³.
Step 4: If there is no cube function on the calculator, simply multiply 1378 three times manually.
Step 5: The calculator will display 2,616,683,352.
The cube of any even number is always even, while the cube of any odd number is always odd.
The product of two or more perfect cube numbers is always a perfect cube.
A perfect cube can always be expressed as the product of three identical groups of equal prime factors.
There are some typical errors that students might make during the process of cubing a number. Let us take a look at five of the major mistakes that students might make:
What is the cube and cube root of 1378?
The cube of 1378 is 2,616,683,352 and the cube root of 1378 is approximately 11.072.
First, let’s find the cube of 1378. 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 1378³ = 2,616,683,352. Next, we must find the cube root of 1378.
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 ∛1378 ≈ 11.072. Hence the cube of 1378 is 2,616,683,352 and the cube root of 1378 is approximately 11.072.
If the side length of the cube is 1378 meters, what is the volume?
The volume is 2,616,683,352 cubic meters.
Use the volume formula for a cube V = Side³. Substitute 1378 for the side length: V = 1378³ = 2,616,683,352 cubic meters.
How much larger is 1378³ than 1000³?
1378³ – 1000³ = 1,616,683,352.
First find the cube of 1378³, that is 2,616,683,352.
Next, find the cube of 1000³, which is 1,000,000,000.
Now, find the difference between them using the subtraction method. 2,616,683,352 – 1,000,000,000 = 1,616,683,352.
Therefore, the 1378³ is 1,616,683,352 larger than 1000³.
If a cube with a side length of 1378 meters is compared to a cube with a side length of 500 meters, how much larger is the volume of the larger cube?
The volume of the cube with a side length of 1378 meters is 2,616,683,352 cubic meters.
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object).
Cubing 1378 means multiplying 1378 by itself three times: 1378 × 1378 = 1,899,684, and then 1,899,684 × 1378 = 2,616,683,352.
The unit of volume is cubic meters (m³), because we are calculating the space inside the cube.
Therefore, the volume of the cube is 2,616,683,352 cubic meters.
Estimate the cube of 1377 using the cube of 1378.
The cube of 1377 is approximately 2,616,683,352.
First, identify the cube of 1378, The cube of 1378 is 1378³ = 2,616,683,352. Since 1377 is only a tiny bit less than 1378, the cube of 1377 will be almost the same as the cube of 1378.
The cube of 1377 is approximately 2,616,683,352 because the difference between 1377 and 1378 is very small. So, we can approximate the value as 2,616,683,352.
