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 cubes of 1279.
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 1279 can be written as 1279³, which is the exponential form. Or it can also be written in arithmetic form as, 1279 × 1279 × 1279.
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 you 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. 1279³ = 1279 × 1279 × 1279
Step 2: You get 2,091,692,239 as the answer. Hence, the cube of 1279 is 2,091,692,239.
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 1279 into two parts, as 1200 and 79. Let a = 1200 and b = 79, so a + b = 1279
Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³.
Step 3: Calculate each term: a³ = 1200³ 3a²b = 3 × 1200² × 79 3ab² = 3 × 1200 × 79² b³ = 79³
Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (1200 + 79)³ = 1200³ + 3 × 1200² × 79 + 3 × 1200 × 79² + 79³ 1279³ = 1,728,000,000 + 341,280,000 + 224,568,000 + 493,039 1279³ = 2,091,692,239
Step 5: Hence, the cube of 1279 is 2,091,692,239.
To find the cube of 1279 using a calculator, input the number 1279 and use the cube function (if available) or multiply 1279 × 1279 × 1279.
This operation calculates the value of 1279³, resulting in 2,091,692,239. 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 2, 7, 9. Step 3: If the calculator has a cube function, press it to calculate 1279³.
Step 4: If there is no cube function on the calculator, simply multiply 1279 three times manually.
Step 5: The calculator will display 2,091,692,239.
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 might occur during the process of cubing a number.
Let us take a look at five of the major mistakes that might happen:
What is the cube and cube root of 1279?
The cube of 1279 is 2,091,692,239 and the cube root of 1279 is approximately 10.79.
First, let’s find the cube of 1279. 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 1279³ = 2,091,692,239. Next, we must find the cube root of 1279.
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 that number.
So, we get ∛1279 ≈ 10.79. Hence the cube of 1279 is 2,091,692,239 and the cube root of 1279 is approximately 10.79.
If the side length of the cube is 1279 cm, what is the volume?
The volume is 2,091,692,239 cm³.
Use the volume formula for a cube V = Side³. Substitute 1279 for the side length: V = 1279³ = 2,091,692,239 cm³.
How much larger is 1279³ than 1200³?
1279³ – 1200³ = 363,692,239.
First find the cube of 1279, which is 2,091,692,239.
Next, find the cube of 1200, which is 1,728,000,000.
Now, find the difference between them using the subtraction method. 2,091,692,239 – 1,728,000,000 = 363,692,239.
Therefore, 1279³ is 363,692,239 larger than 1200³.
If a cube with a side length of 1279 cm is compared to a cube with a side length of 200 cm, how much larger is the volume of the larger cube?
The volume of the cube with a side length of 1279 cm is 2,091,692,239 cm³.
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object).
Cubing 1279 means multiplying 1279 by itself three times: 1279 × 1279 = 1,635,041, and then 1,635,041 × 1279 = 2,091,692,239.
The unit of volume is cubic centimeters (cm³) because we are calculating the space inside the cube.
Therefore, the volume of the cube is 2,091,692,239 cm³.
Estimate the cube of 1278.9 using the cube of 1279.
The cube of 1278.9 is approximately 2,091,692,239.
First, identify the cube of 1279, The cube of 1279 is 1279³ = 2,091,692,239.
Since 1278.9 is only a tiny bit less than 1279, the cube of 1278.9 will be almost the same as the cube of 1279.
The cube of 1278.9 is approximately 2,091,692,239 because the difference between 1278.9 and 1279 is very small.
So, we can approximate the value as 2,091,692,239.
