Cube of 823

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 823 can be written as 823³, which is the exponential form. Or it can also be written in arithmetic form as 823 × 823 × 823.

How to Calculate the Value of Cube of 823

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 to cube the numbers faster and easier without feeling confused or stuck while evaluating the answers. By Multiplication Method Using a Formula Using a Calculator

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. 823³ = 823 × 823 × 823 Step 2: You get 556,476,167 as the answer. Hence, the cube of 823 is 556,476,167.

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 823 into two parts, as 800 and 23. Let a = 800 and b = 23, so a + b = 823 Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³ Step 3: Calculate each term a³ = 800³ 3a²b = 3 × 800² × 23 3ab² = 3 × 800 × 23² b³ = 23³ Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (800 + 23)³ = 800³ + 3 × 800² × 23 + 3 × 800 × 23² + 23³ 823³ = 512,000,000 + 44,160,000 + 1,267,200 + 12,167 823³ = 556,476,167 Step 5: Hence, the cube of 823 is 556,476,167.

Using a Calculator

To find the cube of 823 using a calculator, input the number 823 and use the cube function (if available) or multiply 823 × 823 × 823. This operation calculates the value of 823³, resulting in 556,476,167. It’s a quick way to determine the cube without manual computation. Step 1: Ensure the calculator is functioning properly. Step 2: Press 8 followed by 2 and 3 Step 3: If the calculator has a cube function, press it to calculate 823³. Step 4: If there is no cube function on the calculator, simply multiply 823 three times manually. Step 5: The calculator will display 556,476,167.

Tips and Tricks for the Cube of 823

The cube of any even number is always even, while the cube of any odd number is always odd. The product of two or more perfect cube numbers is always a perfect cube. A perfect cube can always be expressed as the product of three identical groups of equal prime factors.

Problem 1

What is the cube and cube root of 823?

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

The cube of 823 is 556,476,167, and the cube root of 823 is approximately 9.351.

Explanation

First, let’s find the cube of 823. 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 823³ = 556,476,167. Next, we must find the cube root of 823. We know that the cube root of a number, such that ∛x = y Where x is the given number, and y is the cube root value of the number. So, we get ∛823 ≈ 9.351. Hence, the cube of 823 is 556,476,167, and the cube root of 823 is approximately 9.351.

Problem 2

If the side length of the cube is 823 cm, what is the volume?

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

The volume is 556,476,167 cm³.

Explanation

Use the volume formula for a cube V = Side³. Substitute 823 for the side length: V = 823³ = 556,476,167 cm³.

Problem 3

How much larger is 823³ than 723³?

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

823³ – 723³ = 230,483,367.

Explanation

First, find the cube of 823, which is 556,476,167. Next, find the cube of 723, which is 325,992,800. Now, find the difference between them using the subtraction method. 556,476,167 – 325,992,800 = 230,483,367. Therefore, 823³ is 230,483,367 larger than 723³.

Problem 4

If a cube with a side length of 823 cm is compared to a cube with a side length of 123 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 823 cm is 556,476,167 cm³.

Explanation

To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object). Cubing 823 means multiplying 823 by itself three times: 823 × 823 = 677,329, and then 677,329 × 823 = 556,476,167. The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube. Therefore, the volume of the cube is 556,476,167 cm³.

Problem 5

Estimate the cube of 822.9 using the cube of 823.

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

The cube of 822.9 is approximately 556,476,167.

Explanation

First, identify the cube of 823, The cube of 823 is 823³ = 556,476,167. Since 822.9 is only a tiny bit less than 823, the cube of 822.9 will be almost the same as the cube of 823. The cube of 822.9 is approximately 556,476,167 because the difference between 822.9 and 823 is very small. So, we can approximate the value as 556,476,167.
