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 828.
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 828 can be written as 828³, which is the exponential form. Or it can also be written in arithmetic form as 828 × 828 × 828.
In order to check whether a number is a cube number or not, we can use the following three methods, such as the 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
The multiplication method is a process in mathematics used to find the product of numbers 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. 828³ = 828 × 828 × 828 Step 2: You get 568,002,024 as the answer. Hence, the cube of 828 is 568,002,024.
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 828 into two parts, as 800 and 28. Let a = 800 and b = 28, so a + b = 828 Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³ Step 3: Calculate each term a³ = 800³ 3a²b = 3 × 800² × 28 3ab² = 3 × 800 × 28² b³ = 28³ Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (800 + 28)³ = 800³ + 3 × 800² × 28 + 3 × 800 × 28² + 28³ 828³ = 512,000,000 + 53,760,000 + 18,816,000 + 21,952 828³ = 568,002,024 Step 5: Hence, the cube of 828 is 568,002,024.
To find the cube of 828 using a calculator, input the number 828 and use the cube function (if available) or multiply 828 × 828 × 828. This operation calculates the value of 828³, resulting in 568,002,024. It’s a quick way to determine the cube without manual computation. Step 1: Ensure the calculator is functioning properly. Step 2: Press 8, 2, and 8 Step 3: If the calculator has a cube function, press it to calculate 828³. Step 4: If there is no cube function on the calculator, simply multiply 828 three times manually. Step 5: The calculator will display 568,002,024.
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.
There are some typical errors that might occur during the process of cubing a number. Let us take a look at five of the major mistakes that might be made:
What is the cube and cube root of 828?
The cube of 828 is 568,002,024 and the cube root of 828 is approximately 9.465.
First, let’s find the cube of 828. We know that the cube of a number is x³ = y, where x is the given number, and y is the cubed value of that number. So, we get 828³ = 568,002,024. Next, we must find the cube root of 828. 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 ∛828 ≈ 9.465. Hence, the cube of 828 is 568,002,024 and the cube root of 828 is approximately 9.465.
If the side length of the cube is 828 cm, what is the volume?
The volume is 568,002,024 cm³.
Use the volume formula for a cube V = Side³. Substitute 828 for the side length: V = 828³ = 568,002,024 cm³.
How much larger is 828³ than 800³?
828³ – 800³ = 56,002,024.
First, find the cube of 828, which is 568,002,024. Next, find the cube of 800, which is 512,000,000. Now, find the difference between them using the subtraction method. 568,002,024 – 512,000,000 = 56,002,024. Therefore, 828³ is 56,002,024 larger than 800³.
If a cube with a side length of 828 cm is compared to a cube with a side length of 28 cm, how much larger is the volume of the larger cube?
The volume of the cube with a side length of 828 cm is 568,002,024 cm³.
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object). Cubing 828 means multiplying 828 by itself three times: 828 × 828 = 685,584, and then 685,584 × 828 = 568,002,024. The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube. Therefore, the volume of the cube is 568,002,024 cm³.
Estimate the cube of 827.9 using the cube of 828.
The cube of 827.9 is approximately 568,002,024.
First, identify the cube of 828. The cube of 828 is 828³ = 568,002,024. Since 827.9 is only a tiny bit less than 828, the cube of 827.9 will be almost the same as the cube of 828. The cube of 827.9 is approximately 568,002,024 because the difference between 827.9 and 828 is very small. So, we can approximate the value as 568,002,024.
Binomial Formula: It is an algebraic expression used to expand the powers of a number, written as (a + b)ⁿ, where ‘n’ is a positive integer raised to the base. The formula is used to find the square and cube of a number. Cube of a Number: Multiplying a number by itself three times is called the cube of a number. Exponential Form: It is a way of expressing numbers using a base and an exponent (or power), where the exponent value indicates how many times the base is multiplied by itself. For example, 2³ represents 2 × 2 × 2, which equals 8. Cube Root: The cube root of a number is a value that, when multiplied by itself three times, gives the original number. Volume of a Cube: The amount of space occupied by a cube, calculated as the side length raised to the power of three.
