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 cubes of 212.
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 212 can be written as 212³, which is the exponential form. Or it can also be written in arithmetic form as, 212 × 212 × 212.
In order to check whether a number is a cube number or not, we can use the following three methods: multiplication method, 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. 212³ = 212 × 212 × 212 Step 2: You get 9,540,928 as the answer. Hence, the cube of 212 is 9,540,928.
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 212 into two parts, as 200 and 12. Let a = 200 and b = 12, so a + b = 212 Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³ Step 3: Calculate each term a³ = 200³ 3a²b = 3 × 200² × 12 3ab² = 3 × 200 × 12² b³ = 12³ Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (200 + 12)³ = 200³ + 3 × 200² × 12 + 3 × 200 × 12² + 12³ 212³ = 8,000,000 + 1,440,000 + 576,000 + 1,728 212³ = 9,540,928 Step 5: Hence, the cube of 212 is 9,540,928.
To find the cube of 212 using a calculator, input the number 212 and use the cube function (if available) or multiply 212 × 212 × 212. This operation calculates the value of 212³, resulting in 9,540,928. It’s a quick way to determine the cube without manual computation. Step 1: Ensure the calculator is functioning properly. Step 2: Press 2 followed by 1 and 2 Step 3: If the calculator has a cube function, press it to calculate 212³. Step 4: If there is no cube function on the calculator, simply multiply 212 three times manually. Step 5: The calculator will display 9,540,928.
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 212?
The cube of 212 is 9,540,928 and the cube root of 212 is 5.978.
First, let’s find the cube of 212. We know that 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 212³ = 9,540,928 Next, we must find the cube root of 212 We know that cube root of a number ‘x’, such that ³√x = y Where ‘x’ is the given number, and y is the cube root value of the number So, we get ³√212 = 5.978 Hence the cube of 212 is 9,540,928 and the cube root of 212 is approximately 5.978.
If the side length of the cube is 212 cm, what is the volume?
The volume is 9,540,928 cm³.
Use the volume formula for a cube V = Side³. Substitute 212 for the side length: V = 212³ = 9,540,928 cm³.
How much larger is 212³ than 200³?
212³ – 200³ = 1,540,928.
First find the cube of 212³, that is 9,540,928 Next, find the cube of 200³, which is 8,000,000 Now, find the difference between them using the subtraction method. 9,540,928 – 8,000,000 = 1,540,928 Therefore, 212³ is 1,540,928 larger than 200³.
If a cube with a side length of 212 cm is compared to a cube with a side length of 12 cm, how much larger is the volume of the larger cube?
The volume of the cube with a side length of 212 cm is 9,540,928 cm³
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object). Cubing 212 means multiplying 212 by itself three times: 212 × 212 = 44,944, and then 44,944 × 212 = 9,540,928. The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube. Therefore, the volume of the cube is 9,540,928 cm³.
Estimate the cube 211.9 using the cube 212.
The cube of 211.9 is approximately 9,540,928.
First, identify the cube of 212, The cube of 212 is 212³ = 9,540,928. Since 211.9 is only a tiny bit less than 212, the cube of 211.9 will be almost the same as the cube of 212. The cube of 211.9 is approximately 9,540,928 because the difference between 211.9 and 212 is very small. So, we can approximate the value as 9,540,928.
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. Cube Root: The process of finding a number which, when multiplied by itself three times, gives the original number. For example, the cube root of 8 is 2. Perfect Cube: A number that can be expressed as the cube of an integer. For example, 27 is a perfect cube because it is 3³.
