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 630.
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 630 can be written as 630³, which is the exponential form. Or it can also be written in arithmetic form as, 630 × 630 × 630.
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 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. 630³ = 630 × 630 × 630
Step 2: You get 250,047,000 as the answer. Hence, the cube of 630 is 250,047,000.
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 630 into two parts, as 600 and 30. Let a = 600 and b = 30, so a + b = 630
Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³
Step 3: Calculate each term
a³ = 600³
3a²b = 3 × 600² × 30
3ab² = 3 × 600 × 30²
b³ = 30³
Step 4: Add all the terms together:
(a + b)³ = a³ + 3a²b + 3ab² + b³
(600 + 30)³ = 600³ + 3 × 600² × 30 + 3 × 600 × 30² + 30³
630³ = 216,000,000 + 32,400,000 + 16,200,000 + 27,000
630³ = 250,047,000
Step 5: Hence, the cube of 630 is 250,047,000.
To find the cube of 630 using a calculator, input the number 630 and use the cube function (if available) or multiply 630 × 630 × 630. This operation calculates the value of 630³, resulting in 250,047,000. It’s a quick way to determine the cube without manual computation.
Step 1: Ensure the calculator is functioning properly.
Step 2: Press 6 followed by 3 and then 0
Step 3: If the calculator has a cube function, press it to calculate 630³.
Step 4: If there is no cube function on the calculator, simply multiply 630 three times manually.
Step 5: The calculator will display 250,047,000.
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 630?
The cube of 630 is 250,047,000 and the cube root of 630 is approximately 8.5499.
First, let’s find the cube of 630. 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 630³ = 250,047,000
Next, we must find the cube root of 630 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 ∛630 ≈ 8.5499
Hence, the cube of 630 is 250,047,000 and the cube root of 630 is approximately 8.5499.
If the side length of the cube is 630 cm, what is the volume?
The volume is 250,047,000 cm³.
Use the volume formula for a cube V = Side³.
Substitute 630 for the side length: V = 630³ = 250,047,000 cm³.
How much larger is 630³ than 600³?
630³ – 600³ = 34,047,000.
First find the cube of 630³, that is 250,047,000
Next, find the cube of 600³, which is 216,000,000
Now, find the difference between them using the subtraction method.
250,047,000 – 216,000,000 = 34,047,000
Therefore, the 630³ is 34,047,000 larger than 600³.
If a cube with a side length of 630 cm is compared to a cube with a side length of 30 cm, how much larger is the volume of the larger cube?
The volume of the cube with a side length of 630 cm is 250,047,000 cm³.
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object).
Cubing 630 means multiplying 630 by itself three times: 630 × 630 = 396,900, and then 396,900 × 630 = 250,047,000.
The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube.
Therefore, the volume of the cube is 250,047,000 cm³.
Estimate the cube of 629.9 using the cube of 630.
The cube of 629.9 is approximately 250,047,000.
First, identify the cube of 630, The cube of 630 is 630³ = 250,047,000.
Since 629.9 is only a tiny bit less than 630, the cube of 629.9 will be almost the same as the cube of 630.
The cube of 629.9 is approximately 250,047,000 because the difference between 629.9 and 630 is very small.
So, we can approximate the value as 250,047,000.
