Cube of 794

Professor Greenline Explaining Math Concepts

When a number is multiplied by itself thrice, the resultant number is called the cube of a number. Cubing is used while comparing sizes of objects or things with cubic measurements. In this topic, we shall learn about the cube of 794.

Cube of 794

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 794 can be written as 794³, which is the exponential form. Or it can also be written in arithmetic form as, 794 × 794 × 794.

How to Calculate the Value of Cube of 794

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.

By Multiplication Method

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. 794³ = 794 × 794 × 794

 

Step 2: You get 500,021,384 as the answer. Hence, the cube of 794 is 500,021,384.

Professor Greenline from BrightChamps

Using a Formula (a³)

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 794 into two parts. Let a = 700 and b = 94, so a + b = 794

 

Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³

 

Step 3: Calculate each term

 

a³ = 700³

 

3a²b = 3 × 700² × 94

 

3ab² = 3 × 700 × 94²

 

b³ = 94³

 

Step 4: Add all the terms together:

 

(a + b)³ = a³ + 3a²b + 3ab² + b³

 

(700 + 94)³ = 700³ + 3 × 700² × 94 + 3 × 700 × 94² + 94³

 

794³ = 343,000,000 + 138,180,000 + 18,504,400 + 830,584

 

794³ = 500,021,384

 

Step 5: Hence, the cube of 794 is 500,021,384.

Professor Greenline from BrightChamps

Using a Calculator

To find the cube of 794 using a calculator, input the number 794 and use the cube function (if available) or multiply 794 × 794 × 794. This operation calculates the value of 794³, resulting in 500,021,384. It’s a quick way to determine the cube without manual computation.

 

Step 1: Ensure the calculator is functioning properly.

 

Step 2: Press 7 followed by 9 and then 4

 

Step 3: If the calculator has a cube function, press it to calculate 794³.

 

Step 4: If there is no cube function on the calculator, simply multiply 794 three times manually.

 

Step 5: The calculator will display 500,021,384.

Solved Examples on Cube of 794

Ray, the Character from BrightChamps Explaining Math Concepts

Problem 1

What is the cube and cube root of 794?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The cube of 794 is 500,021,384 and the cube root of 794 is approximately 9.283.

Explanation

First, let’s find the cube of 794.

 

We know that the cube of a number is calculated as x³ = y, where x is the given number, and y is the cubed value of that number.

 

So, we get 794³ = 500,021,384.

 

Next, we must find the cube root of 794.

 

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 ∛794 ≈ 9.283.

 

Hence, the cube of 794 is 500,021,384 and the cube root of 794 is approximately 9.283.

Problem 2

If the side length of a cube is 794 cm, what is the volume?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The volume is 500,021,384 cm³.

Explanation

Use the volume formula for a cube V = Side³.

 

Substitute 794 for the side length: V = 794³ = 500,021,384 cm³.

Problem 3

How much larger is 794³ than 694³?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

794³ – 694³ = 328,921,384.

Explanation

First, find the cube of 794³, which is 500,021,384.

 

Next, find the cube of 694³, which is 171,100,000.

 

Now, find the difference between them using the subtraction method: 500,021,384 – 171,100,000 = 328,921,384.

 

Therefore, 794³ is 328,921,384 larger than 694³.

Problem 4

If a cube with a side length of 794 cm is compared to a cube with a side length of 194 cm, how much larger is the volume of the larger cube?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The volume of the cube with a side length of 794 cm is significantly larger than the cube with a side length of 194 cm.

Explanation

To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object).

 

Cubing 794 means multiplying 794 by itself three times: 794 × 794 = 630,436, and then 630,436 × 794 = 500,021,384.

 

The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube.

 

Similarly, the volume of the cube with a side length of 194 cm is 7,306,264 cm³ (since 194³ = 7,306,264).

 

Therefore, the volume of the cube with a side length of 794 cm is significantly larger than the cube with a side length of 194 cm.

Problem 5

Estimate the cube of 793 using the cube of 794.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The cube of 793 is approximately 500,021,384.

Explanation

First, identify the cube of 794: The cube of 794 is 794³ = 500,021,384.

 

Since 793 is only a tiny bit less than 794, the cube of 793 will be almost the same as the cube of 794.

 

The cube of 793 is approximately 500,021,384 because the difference between 793 and 794 is very small.

 

So, we can approximate the value as 500,021,384.
