When a number is multiplied by itself thrice, the resultant number is called the cube of a number. Cubing is used in while comparing sizes of objects or things with cubic measurements. In this topic, we shall learn about cubes of 928.
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 928 can be written as 928³, which is the exponential form. Or it can also be written in arithmetic form as, 928 × 928 × 928.
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. 928³ = 928 × 928 × 928 Step 2: You get 799,714,432 as the answer. Hence, the cube of 928 is 799,714,432.
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 928 into two parts. Let a = 900 and b = 28, so a + b = 928 Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³ Step 3: Calculate each term a³ = 900³ 3a²b = 3 × 900² × 28 3ab² = 3 × 900 × 28² b³ = 28³ Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (900 + 28)³ = 900³ + 3 × 900² × 28 + 3 × 900 × 28² + 28³ 928³ = 729,000,000 + 68,040,000 + 21,168,000 + 21,952 928³ = 799,714,432 Step 5: Hence, the cube of 928 is 799,714,432.
To find the cube of 928 using a calculator, input the number 928 and use the cube function (if available) or multiply 928 × 928 × 928. This operation calculates the value of 928³, resulting in 799,714,432. It’s a quick way to determine the cube without manual computation. Step 1: Ensure the calculator is functioning properly. Step 2: Press 9 followed by 2 and 8 Step 3: If the calculator has a cube function, press it to calculate 928³. Step 4: If there is no cube function on the calculator, simply multiply 928 three times manually. Step 5: The calculator will display 799,714,432.
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 928?
The cube of 928 is 799,714,432 and the cube root of 928 is approximately 9.741.
First, let’s find the cube of 928. 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 928³ = 799,714,432 Next, we must find the cube root of 928 We know that 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 ∛928 ≈ 9.741 Hence the cube of 928 is 799,714,432 and the cube root of 928 is approximately 9.741.
If the side length of the cube is 928 cm, what is the volume?
The volume is 799,714,432 cm³.
Use the volume formula for a cube V = Side³. Substitute 928 for the side length: V = 928³ = 799,714,432 cm³.
How much larger is 928³ than 900³?
928³ – 900³ = 70,714,432.
First find the cube of 928³, that is 799,714,432 Next, find the cube of 900³, which is 729,000,000 Now, find the difference between them using the subtraction method. 799,714,432 – 729,000,000 = 70,714,432 Therefore, 928³ is 70,714,432 larger than 900³.
If a cube with a side length of 928 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 928 cm is 799,714,432 cm³.
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object). Cubing 928 means multiplying 928 by itself three times: 928 × 928 = 861,184, and then 861,184 × 928 = 799,714,432. The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube. Therefore, the volume of the cube is 799,714,432 cm³.
Estimate the cube 927.5 using the cube 928.
The cube of 927.5 is approximately 799,714,432.
First, identify the cube of 928, The cube of 928 is 928³ = 799,714,432. Since 927.5 is only a tiny bit less than 928, the cube of 927.5 will be almost the same as the cube of 928. The cube of 927.5 is approximately 799,714,432 because the difference between 927.5 and 928 is very small. So, we can approximate the value as 799,714,432.
Binomial Formula: 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 is the cube of an integer. For example, 27 is a perfect cube because it is 3³. Cube Root: The cube root of a number is a value that, when multiplied by itself three times, gives the original number. For example, the cube root of 27 is 3.
