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 651.
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 651 can be written as 651³, which is the exponential form. Or it can also be written in arithmetic form as, 651 × 651 × 651.
In order to check whether a number is a cube number or not, we can use the following three methods: the 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. 651³ = 651 × 651 × 651
Step 2: You get 275,651,751 as the answer. Hence, the cube of 651 is 275,651,751.
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 651 into two parts. Let a = 650 and b = 1, so a + b = 651
Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³
Step 3: Calculate each term
a³ = 650³
3a²b = 3 × 650² × 1
3ab² = 3 × 650 × 1²
b³ = 1³
Step 4: Add all the terms together:
(a + b)³ = a³ + 3a²b + 3ab² + b³
(650 + 1)³ = 650³ + 3 × 650² × 1 + 3 × 650 × 1² + 1³
651³ = 274,625,000 + 1,267,500 + 1,950 + 1
651³ = 275,651,751
Step 5: Hence, the cube of 651 is 275,651,751.
To find the cube of 651 using a calculator, input the number 651 and use the cube function (if available) or multiply 651 × 651 × 651. This operation calculates the value of 651³, resulting in 275,651,751. 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 5 and 1
Step 3: If the calculator has a cube function, press it to calculate 651³.
Step 4: If there is no cube function on the calculator, simply multiply 651 three times manually.
Step 5: The calculator will display 275,651,751.
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 651?
The cube of 651 is 275,651,751 and the cube root of 651 is approximately 8.695.
First, let’s find the cube of 651.
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 651³ = 275,651,751.
Next, we must find the cube root of 651. 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 the number.
So, we get ∛651 ≈ 8.695.
Hence, the cube of 651 is 275,651,751 and the cube root of 651 is approximately 8.695.
If the side length of a cube is 651 cm, what is the volume?
The volume is 275,651,751 cm³.
Use the volume formula for a cube V = Side³.
Substitute 651 for the side length: V = 651³ = 275,651,751 cm³.
How much larger is 651³ than 401³?
651³ – 401³ = 270,333,350.
First, find the cube of 651, which is 275,651,751. Next, find the cube of 401, which is 5,318,401.
Now, find the difference between them using the subtraction method.
275,651,751 – 5,318,401 = 270,333,350.
Therefore, 651³ is 270,333,350 larger than 401³.
If a cube with a side length of 651 cm is compared to a cube with a side length of 150 cm, how much larger is the volume of the larger cube?
The volume of the cube with a side length of 651 cm is 275,651,751 cm³.
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object).
Cubing 651 means multiplying 651 by itself three times: 651 × 651 = 423,801, and then 423,801 × 651 = 275,651,751.
The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube.
Therefore, the volume of the cube is 275,651,751 cm³.
Estimate the cube 650.5 using the cube 651.
The cube of 650.5 is approximately 275,651,751.
First, identify the cube of 651. The cube of 651 is 651³ = 275,651,751.
Since 650.5 is only a tiny bit less than 651, the cube of 650.5 will be almost the same as the cube of 651.
The cube of 650.5 is approximately 275,651,751 because the difference between 650.5 and 651 is very small.
So, we can approximate the value as 275,651,751.
