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 767.
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, as a negative number multiplied by itself three times results in a negative number.
The cube of 767 can be written as 767³, which is the exponential form. Or it can also be written in arithmetic form as 767 × 767 × 767.
To determine 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 students cube numbers faster and more easily 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. 767³ = 767 × 767 × 767
Step 2: You get 451,574,383 as the answer. Hence, the cube of 767 is 451,574,383.
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 767 into two parts. Let a = 700 and b = 67, so a + b = 767
Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³
Step 3: Calculate each term
a³ = 700³
3a²b = 3 × 700² × 67
3ab² = 3 × 700 × 67²
b³ = 67³
Step 4: Add all the terms together:
(a + b)³ = a³ + 3a²b + 3ab² + b³
(700 + 67)³ = 700³ + 3 × 700² × 67 + 3 × 700 × 67² + 67³
767³ = 343000000 + 98742000 + 9945300 + 300763
767³ = 451,574,383
Step 5: Hence, the cube of 767 is 451,574,383.
To find the cube of 767 using a calculator, input the number 767 and use the cube function (if available) or multiply 767 × 767 × 767. This operation calculates the value of 767³, resulting in 451,574,383. It’s a quick way to determine the cube without manual computation.
Step 1: Ensure the calculator is functioning properly.
Step 2: Enter 7, 6, and 7
Step 3: If the calculator has a cube function, press it to calculate 767³.
Step 4: If there is no cube function on the calculator, simply multiply 767 three times manually.
Step 5: The calculator will display 451,574,383.
There are some typical errors that students might make during the process of cubing a number. Let us take a look at five of the major mistakes that students might make:
What is the cube and cube root of 767?
The cube of 767 is 451,574,383, and the cube root of 767 is approximately 9.2516.
First, let’s find the cube of 767.
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 767³ = 451,574,383.
Next, we must find the cube root of 767.
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 ∛767 ≈ 9.2516.
If the side length of the cube is 767 cm, what is the volume?
The volume is 451,574,383 cm³.
Use the volume formula for a cube V = Side³.
Substitute 767 for the side length: V = 767³ = 451,574,383 cm³.
How much larger is 767³ than 667³?
767³ – 667³ = 289,343,000.
First, find the cube of 767³, which is 451,574,383.
Next, find the cube of 667³, which is 162,231,383.
Now, find the difference between them using the subtraction method. 451,574,383 – 162,231,383 = 289,343,000.
Therefore, 767³ is 289,343,000 larger than 667³.
If a cube with a side length of 767 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 767 cm is 451,574,383 cm³.
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object).
Cubing 767 means multiplying 767 by itself three times: 767 × 767 = 588,289, and then 588,289 × 767 = 451,574,383.
The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube.
Therefore, the volume of the cube is 451,574,383 cm³.
Estimate the cube of 766.9 using the cube of 767.
The cube of 766.9 is approximately 451,574,383.
First, identify the cube of 767: The cube of 767 is 767³ = 451,574,383.
Since 766.9 is only a tiny bit less than 767, the cube of 766.9 will be almost the same as the cube of 767.
The cube of 766.9 is approximately 451,574,383 because the difference between 766.9 and 767 is very small.
So, we can approximate the value as 451,574,383.
