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 847.
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 847 can be written as 847³, which is the exponential form. Or it can also be written in arithmetic form as 847 × 847 × 847.
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 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. 847³ = 847 × 847 × 847 Step 2: You get 607,573,023 as the answer. Hence, the cube of 847 is 607,573,023.
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 847 into two parts, such as 800 and 47. Let a = 800 and b = 47, so a + b = 847. Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³. Step 3: Calculate each term: a³ = 800³ 3a²b = 3 × 800² × 47 3ab² = 3 × 800 × 47² b³ = 47³ Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (800 + 47)³ = 800³ + 3 × 800² × 47 + 3 × 800 × 47² + 47³ 847³ = 512,000,000 + 150,720,000 + 53,136,000 + 103,823 847³ = 607,573,023 Step 5: Hence, the cube of 847 is 607,573,023.
To find the cube of 847 using a calculator, input the number 847 and use the cube function (if available) or multiply 847 × 847 × 847. This operation calculates the value of 847³, resulting in 607,573,023. It’s a quick way to determine the cube without manual computation. Step 1: Ensure the calculator is functioning properly. Step 2: Input 847. Step 3: If the calculator has a cube function, press it to calculate 847³. Step 4: If there is no cube function on the calculator, simply multiply 847 three times manually. Step 5: The calculator will display 607,573,023.
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 847?
The cube of 847 is 607,573,023, and the cube root of 847 is approximately 9.448.
First, let’s find the cube of 847. We know that the cube of a number, x³ = y, where x is the given number, and y is the cubed value of that number. So, we get 847³ = 607,573,023. Next, we must find the cube root of 847. 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. Therefore, ∛847 is approximately 9.448. Hence, the cube of 847 is 607,573,023, and the cube root of 847 is approximately 9.448.
If the side length of the cube is 847 cm, what is the volume?
The volume is 607,573,023 cm³.
Use the volume formula for a cube V = Side³. Substitute 847 for the side length: V = 847³ = 607,573,023 cm³.
How much larger is 847³ than 800³?
847³ – 800³ = 95,573,023.
First, find the cube of 847³, which is 607,573,023. Next, find the cube of 800³, which is 512,000,000. Now, find the difference between them using the subtraction method. 607,573,023 – 512,000,000 = 95,573,023. Therefore, 847³ is 95,573,023 larger than 800³.
If a cube with a side length of 847 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 847 cm is 607,573,023 cm³.
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object). Cubing 847 means multiplying 847 by itself three times: 847 × 847 = 717,409, and then 717,409 × 847 = 607,573,023. The unit of volume is cubic centimeters (cm³) because we are calculating the space inside the cube. Therefore, the volume of the cube is 607,573,023 cm³.
Estimate the cube of 846.9 using the cube of 847.
The cube of 846.9 is approximately 607,573,023.
First, identify the cube of 847. The cube of 847 is 847³ = 607,573,023. Since 846.9 is only a tiny bit less than 847, the cube of 846.9 will be almost the same as the cube of 847. The cube of 846.9 is approximately 607,573,023 because the difference between 846.9 and 847 is very small. So, we can approximate the value as 607,573,023.
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, equaling 8. Perfect Cube: A number that can be expressed as the cube of an integer. Volume of a Cube: The amount of space occupied by a cube, calculated as the side length raised to the third power.
