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 825.
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 by itself three times results in a negative number. The cube of 825 can be written as 825³, which is the exponential form. Or it can also be written in arithmetic form as, 825 × 825 × 825.
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 Using a Formula Using a Calculator
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. 825³ = 825 × 825 × 825 Step 2: You get 561,515,625 as the answer. Hence, the cube of 825 is 561,515,625.
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 825 into two parts, as 800 and 25. Let a = 800 and b = 25, so a + b = 825 Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³ Step 3: Calculate each term a³ = 800³ 3a²b = 3 × 800² × 25 3ab² = 3 × 800 × 25² b³ = 25³ Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (800 + 25)³ = 800³ + 3 × 800² × 25 + 3 × 800 × 25² + 25³ 825³ = 512,000,000 + 48,000,000 + 15,000,000 + 15,625 825³ = 561,515,625 Step 5: Hence, the cube of 825 is 561,515,625.
To find the cube of 825 using a calculator, input the number 825 and use the cube function (if available) or multiply 825 × 825 × 825. This operation calculates the value of 825³, resulting in 561,515,625. 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 5 Step 3: If the calculator has a cube function, press it to calculate 825³. Step 4: If there is no cube function on the calculator, simply multiply 825 three times manually. Step 5: The calculator will display 561,515,625.
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 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 825?
The cube of 825 is 561,515,625 and the cube root of 825 is approximately 9.422.
First, let’s find the cube of 825. 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 825³ = 561,515,625 Next, we must find the cube root of 825 We know that the cube root of a number ‘x’, such that ∛x = y Where ‘x’ is the given number, and ‘y’ is the cube root value of the number So, we get ∛825 ≈ 9.422 Hence, the cube of 825 is 561,515,625 and the cube root of 825 is approximately 9.422.
If the side length of a cube is 825 cm, what is the volume?
The volume is 561,515,625 cm³.
Use the volume formula for a cube V = Side³. Substitute 825 for the side length: V = 825³ = 561,515,625 cm³.
How much larger is 825³ than 800³?
825³ – 800³ = 49,515,625.
First, find the cube of 825³, that is 561,515,625 Next, find the cube of 800³, which is 512,000,000 Now, find the difference between them using the subtraction method. 561,515,625 – 512,000,000 = 49,515,625 Therefore, 825³ is 49,515,625 larger than 800³.
If a cube with a side length of 825 cm is compared to a cube with a side length of 25 cm, how much larger is the volume of the larger cube?
The volume of the cube with a side length of 825 cm is 561,515,625 cm³.
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object). Cubing 825 means multiplying 825 by itself three times: 825 × 825 = 680,625, and then 680,625 × 825 = 561,515,625. The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube. Therefore, the volume of the cube is 561,515,625 cm³.
Estimate the cube of 824.9 using the cube of 825.
The cube of 824.9 is approximately 561,515,625.
First, identify the cube of 825, The cube of 825 is 825³ = 561,515,625. Since 824.9 is only a tiny bit less than 825, the cube of 824.9 will be almost the same as the cube of 825. The cube of 824.9 is approximately 561,515,625 because the difference between 824.9 and 825 is very small. So, we can approximate the value as 561,515,625.
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 equals 8. Perfect Cube: A number that is the cube of an integer is called a perfect cube. Volume Formula: The formula for finding the volume of a cube is V = Side³, where 'Side' is the length of one edge of the cube.
