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 1431.
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 multiplying a negative number by itself three times results in a negative number.
The cube of 1431 can be written as 1431³, which is the exponential form. Or it can also be written in arithmetic form as, 1431 × 1431 × 1431.
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.
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. 1431³ = 1431 × 1431 × 1431
Step 2: You get 2,932,931,191 as the answer. Hence, the cube of 1431 is 2,932,931,191.
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 1431 into two parts. Let a = 1400 and b = 31, so a + b = 1431
Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³
Step 3: Calculate each term a³ = 1400³ , 3a²b = 3 × 1400² × 31 , 3ab² = 3 × 1400 × 31² , b³ = 31³
Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³
(1400 + 31)³ = 1400³ + 3 × 1400² × 31 + 3 × 1400 × 31² + 31³ 1
431³ = 2,744,000,000 + 182,280,000 + 58,212,000 + 29,791
1431³ = 2,932,931,191 Step 5:
Hence, the cube of 1431 is 2,932,931,191.
To find the cube of 1431 using a calculator, input the number 1431 and use the cube function (if available) or multiply 1431 × 1431 × 1431. This operation calculates the value of 1431³, resulting in 2,932,931,191. It’s a quick way to determine the cube without manual computation.
Step 1: Ensure the calculator is functioning properly.
Step 2: Input 1431
Step 3: If the calculator has a cube function, press it to calculate 1431³.
Step 4: If there is no cube function on the calculator, simply multiply 1431 three times manually.
Step 5: The calculator will display 2,932,931,191.
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 1431?
The cube of 1431 is 2,932,931,191 and the cube root of 1431 is approximately 11.079.
First, let’s find the cube of 1431. 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 1431³ = 2,932,931,191. Next, we must find the cube root of 1431. 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√1431 ≈ 11.079.
Hence the cube of 1431 is 2,932,931,191 and the cube root of 1431 is approximately 11.079.
If the side length of the cube is 1431 cm, what is the volume?
The volume is 2,932,931,191 cm³.
Use the volume formula for a cube V = Side³.
Substitute 1431 for the side length: V = 1431³ = 2,932,931,191 cm³.
How much larger is 1431³ than 1000³?
1431³ – 1000³ = 2,932,931,191 - 1,000,000,000 = 1,932,931,191.
First find the cube of 1431, that is 2,932,931,191.
Next, find the cube of 1000, which is 1,000,000,000.
Now, find the difference between them using the subtraction method. 2,932,931,191 - 1,000,000,000 = 1,932,931,191.
Therefore, 1431³ is 1,932,931,191 larger than 1000³.
If a cube with a side length of 1431 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 1431 cm is 2,932,931,191 cm³.
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object).
Cubing 1431 means multiplying 1431 by itself three times: 1431 × 1431 = 2,048,961, and then 2,048,961 × 1431 = 2,932,931,191.
The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube.
Therefore, the volume of the cube is 2,932,931,191 cm³.
Estimate the cube 1430.9 using the cube 1431.
The cube of 1430.9 is approximately 2,932,931,191.
First, identify the cube of 1431. The cube of 1431 is 1431³ = 2,932,931,191.
Since 1430.9 is only a tiny bit less than 1431, the cube of 1430.9 will be almost the same as the cube of 1431. The cube of 1430.9 is approximately 2,932,931,191 because the difference between 1430.9 and 1431 is very small.
So, we can approximate the value as 2,932,931,191.
