Cube of 1025

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 1025 can be written as 1025³, which is the exponential form. Or it can also be written in arithmetic form as, 1025 × 1025 × 1025.

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 numbers 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. 1025³ = 1025 × 1025 × 1025

Step 2: You get 1,076,890,625 as the answer. Hence, the cube of 1025 is 1,076,890,625.

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 1025 into two parts. Let a = 1000 and b = 25, so a + b = 1025

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

Step 3: Calculate each term

a³ = 1000³

3a²b = 3 × 1000² × 25

3ab² = 3 × 1000 × 25²

b³ = 25³

Step 4: Add all the terms together:

(a + b)³ = a³ + 3a²b + 3ab² + b³

(1000 + 25)³ = 1000³ + 3 × 1000² × 25 + 3 × 1000 × 25² + 25³

1025³ = 1,000,000,000 + 75,000,000 + 1,875,000 + 15,625

1025³ = 1,076,890,625

Step 5: Hence, the cube of 1025 is 1,076,890,625.

To find the cube of 1025 using a calculator, input the number 1025 and use the cube function (if available) or multiply 1025 × 1025 × 1025. This operation calculates the value of 1025³, resulting in 1,076,890,625. It’s a quick way to determine the cube without manual computation.

Step 1: Ensure the calculator is functioning properly.

Step 2: Press 1, 0, 2, and 5

Step 3: If the calculator has a cube function, press it to calculate 1025³.

Step 4: If there is no cube function on the calculator, simply multiply 1025 three times manually.

Step 5: The calculator will display 1,076,890,625.

• 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 the powers of a number, written as (a + b)ⁿ, where ‘n’ is a positive integer raised to the base. The formula is useful for finding the 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 to 8.

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

• Cube Root: The number that, when multiplied by itself three times, gives the original number.
