When a number is multiplied by itself thrice, the resultant number is called the cube of a number. Cubing is used in comparing sizes of objects or things with cubic measurements. In this topic, we shall learn about the cube of 802.
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 802 can be written as 802³, which is the exponential form. Or it can also be written in arithmetic form as, 802 × 802 × 802.
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. 802³ = 802 × 802 × 802 Step 2: You get 516,221,608 as the answer. Hence, the cube of 802 is 516,221,608.
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 802 into two parts. Let a = 800 and b = 2, so a + b = 802 Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³ Step 3: Calculate each term. a³ = 800³ 3a²b = 3 × 800² × 2 3ab² = 3 × 800 × 2² b³ = 2³ Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (800 + 2)³ = 800³ + 3 × 800² × 2 + 3 × 800 × 2² + 2³ 802³ = 512,000,000 + 3,840,000 + 9,600 + 8 802³ = 516,221,608 Step 5: Hence, the cube of 802 is 516,221,608.
To find the cube of 802 using a calculator, input the number 802 and use the cube function (if available) or multiply 802 × 802 × 802. This operation calculates the value of 802³, resulting in 516,221,608. It’s a quick way to determine the cube without manual computation. Step 1: Ensure the calculator is functioning properly. Step 2: Press 8, 0, followed by 2 Step 3: If the calculator has a cube function, press it to calculate 802³. Step 4: If there is no cube function on the calculator, simply multiply 802 three times manually. Step 5: The calculator will display 516,221,608.
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 802?
The cube of 802 is 516,221,608 and the cube root of 802 is approximately 9.282.
First, let’s find the cube of 802. 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 802³ = 516,221,608 Next, we must find the cube root of 802 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√802 ≈ 9.282 Hence, the cube of 802 is 516,221,608 and the cube root of 802 is approximately 9.282.
If the side length of the cube is 802 cm, what is the volume?
The volume is 516,221,608 cm³.
Use the volume formula for a cube V = Side³. Substitute 802 for the side length: V = 802³ = 516,221,608 cm³.
How much larger is 802³ than 402³?
802³ – 402³ = 496,236,208.
First find the cube of 802³, that is 516,221,608 Next, find the cube of 402³, which is 19,985,400 Now, find the difference between them using the subtraction method. 516,221,608 – 19,985,400 = 496,236,208 Therefore, the 802³ is 496,236,208 larger than 402³.
If a cube with a side length of 802 cm is compared to a cube with a side length of 2 cm, how much larger is the volume of the larger cube?
The volume of the cube with a side length of 802 cm is 516,221,608 cm³
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object). Cubing 802 means multiplying 802 by itself three times: 802 × 802 = 643,204, and then 643,204 × 802 = 516,221,608. The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube. Therefore, the volume of the cube is 516,221,608 cm³.
Estimate the cube 801.5 using the cube 802.
The cube of 801.5 is approximately 516,221,608.
First, identify the cube of 802, The cube of 802 is 802³ = 516,221,608. Since 801.5 is only a tiny bit less than 802, the cube of 801.5 will be almost the same as the cube of 802. The cube of 801.5 is approximately 516,221,608 because the difference between 801.5 and 802 is very small. So, we can approximate the value as 516,221,608.
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: 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 can be expressed as the cube of an integer. For example, 27 is a perfect cube because it equals 3³. Cube Root: A value that, when multiplied by itself three times, gives the original number. For example, the cube root of 27 is 3.
