Cube of 969

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 969 can be written as 969³, which is the exponential form. Or it can also be written in arithmetic form as 969 × 969 × 969.

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 children to cube 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 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. 969³ = 969 × 969 × 969

Step 2: You get 909,853,209 as the answer. Hence, the cube of 969 is 909,853,209.

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 969 into two parts. Let a = 960 and b = 9, so a + b = 969

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

Step 3: Calculate each term

a³ = 960³

3a²b = 3 × 960² × 9

3ab² = 3 × 960 × 9²

b³ = 9³

Step 4: Add all the terms together:

(a + b)³ = a³ + 3a²b + 3ab² + b³

(960 + 9)³ = 960³ + 3 × 960² × 9 + 3 × 960 × 9² + 9³

969³ = 884,736,000 + 248,832 + 23,328 + 729

969³ = 909,853,209

Step 5: Hence, the cube of 969 is 909,853,209.

To find the cube of 969 using a calculator, input the number 969 and use the cube function (if available) or multiply 969 × 969 × 969. This operation calculates the value of 969³, resulting in 909,853,209. It’s a quick way to determine the cube without manual computation.

Step 1: Ensure the calculator is functioning properly.

Step 2: Enter 969

Step 3: If the calculator has a cube function, press it to calculate 969³.

Step 4: If there is no cube function on the calculator, simply multiply 969 three times manually.

Step 5: The calculator will display 909,853,209.

• 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: 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 cube root of a number is a value that, when multiplied by itself twice, gives the original number. It is denoted by the symbol ∛.

• Perfect Cube: A perfect cube is a number that can be expressed as the cube of an integer.
