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 1289.
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 1289 can be written as 1289³, which is the exponential form.
Or it can also be written in arithmetic form as, 1289 × 1289 × 1289.
In order to check whether a number is a cube number or not, we can use the following three methods: 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.
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 multiplication.
It is a fundamental operation that forms the basis for more complex mathematical concepts.
Step 1: Write down the cube of the given number. 1289³ = 1289 × 1289 × 1289
Step 2: You get 2,141,706,089 as the answer. Hence, the cube of 1289 is 2,141,706,089.
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 1289 into two parts. Let a = 1200 and b = 89, so a + b = 1289
Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³
Step 3: Calculate each term a³ = 1200³ 3a²b = 3 × 1200² × 89 3ab² = 3 × 1200 × 89² b³ = 89³
Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (1200 + 89)³ = 1200³ + 3 × 1200² × 89 + 3 × 1200 × 89² + 89³ 1289³ = 1,728,000,000 + 384,480,000 + 28,368,000 + 704,969 1289³ = 2,141,706,089
Step 5: Hence, the cube of 1289 is 2,141,706,089.
To find the cube of 1289 using a calculator, input the number 1289 and use the cube function (if available) or multiply 1289 × 1289 × 1289.
This operation calculates the value of 1289³, resulting in 2,141,706,089. It’s a quick way to determine the cube without manual computation.
Step 1: Ensure the calculator is functioning properly.
Step 2: Press 1, 2, 8, and 9
Step 3: If the calculator has a cube function, press it to calculate 1289³.
Step 4: If there is no cube function on the calculator, simply multiply 1289 three times manually.
Step 5: The calculator will display 2,141,706,089.
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 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 1289?
The cube of 1289 is 2,141,706,089 and the cube root of 1289 is approximately 10.79.
First, let’s find the cube of 1289. We know that the cube of a number x, such that x³ = y Where x is the given number, and y is the cubed value of that number So, we get 1289³ = 2,141,706,089 Next, we must find the cube root of 1289
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 ∛1289 ≈ 10.79 Hence the cube of 1289 is 2,141,706,089 and the cube root of 1289 is approximately 10.79.
If the side length of the cube is 1289 cm, what is the volume?
The volume is 2,141,706,089 cm³.
Use the volume formula for a cube V = Side³. Substitute 1289 for the side length: V = 1289³ = 2,141,706,089 cm³.
How much larger is 1289³ than 1200³?
1289³ – 1200³ = 413,706,089.
First find the cube of 1289, that is 2,141,706,089 Next, find the cube of 1200, which is 1,728,000,000
Now, find the difference between them using the subtraction method. 2,141,706,089 – 1,728,000,000 = 413,706,089
Therefore, 1289³ is 413,706,089 larger than 1200³.
If a cube with a side length of 1289 cm is compared to a cube with a side length of 100 cm, how much larger is the volume of the larger cube?
The volume of the cube with a side length of 1289 cm is 2,141,706,089 cm³
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object).
Cubing 1289 means multiplying 1289 by itself three times: 1289 × 1289 = 1,661,721, and then 1,661,721 × 1289 = 2,141,706,089.
The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube.
Therefore, the volume of the cube is 2,141,706,089 cm³.
Estimate the cube of 1288 using the cube of 1289.
The cube of 1288 is approximately 2,141,706,089.
First, identify the cube of 1289, The cube of 1289 is 1289³ = 2,141,706,089. Since 1288 is only a tiny bit less than 1289, the cube of 1288 will be almost the same as the cube of 1289.
The cube of 1288 is approximately 2,141,706,089 because the difference between 1288 and 1289 is very small.
So, we can approximate the value as 2,141,706,089.
