Cube of 946

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 946 can be written as 946³, which is the exponential form. Or it can also be written in arithmetic form as 946 × 946 × 946.

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.

1. By Multiplication Method
2. Using a Formula
3. 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. 946³ = 946 × 946 × 946

Step 2: Calculate the product to get the answer. Hence, the cube of 946 is 847,072,936.

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 946 into two parts. Let a = 900 and b = 46, so a + b = 946

Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³

Step 3: Calculate each term:

a³ = 900³

3a²b = 3 × 900² × 46

3ab² = 3 × 900 × 46² b³ = 46³

Step 4: Add all the terms together:

(a + b)³ = a³ + 3a²b + 3ab² + b³

(900 + 46)³ = 900³ + 3 × 900² × 46 + 3 × 900 × 46² + 46³

Calculate each part and sum them to find 946³ = 847,072,936.

Step 5: Hence, the cube of 946 is 847,072,936.

To find the cube of 946 using a calculator, input the number 946 and use the cube function (if available) or multiply 946 × 946 × 946. This operation calculates the value of 946³, resulting in 847,072,936. 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 4 and 6.

Step 3: If the calculator has a cube function, press it to calculate 946³.

 Step 4: If there is no cube function on the calculator, simply multiply 946 three times manually.

Step 5: The calculator will display 847,072,936.

• 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.

• Binomial Formula: An algebraic expression used to expand powers of a number, written as (a + b)ⁿ, where ‘n’ is a positive integer. The formula is used to find the powers of numbers.

• 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, 3³ represents 3 × 3 × 3 equals 27.

• Perfect Cube: A number that can be expressed as the product of three identical integers. For example, 8 is a perfect cube because it equals 2 × 2 × 2.

• Volume of a Cube: The space occupied by a cube, calculated by cubing its side length, expressed in cubic units.
