Cube of 948

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 948 can be written as 948³, which is the exponential form. Or it can also be written in arithmetic form as, 948 × 948 × 948.

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 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. 948³ = 948 × 948 × 948

Step 2: You get 851,841,792 as the answer. Hence, the cube of 948 is 851,841,792.

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 948 into two parts. Let a = 900 and b = 48, so a + b = 948

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

Step 3: Calculate each term

a³ = 900³

3a²b = 3 × 900² × 48

3ab² = 3 × 900 × 48²

b³ = 48³

Step 4: Add all the terms together:

(a + b)³ = a³ + 3a²b + 3ab² + b³

(900 + 48)³ = 900³ + 3 × 900² × 48 + 3 × 900 × 48² + 48³

948³ = 729,000,000 + 116,640,000 + 62,208,000 + 110,592

948³ = 851,841,792

Step 5: Hence, the cube of 948 is 851,841,792.

To find the cube of 948 using a calculator, input the number 948 and use the cube function (if available) or multiply 948 × 948 × 948. This operation calculates the value of 948³, resulting in 851,841,792. It’s a quick way to determine the cube without manual computation.

Step 1: Ensure the calculator is functioning properly.

Step 2: Press 9, 4, and 8

Step 3: If the calculator has a cube function, press it to calculate 948³.

Step 4: If there is no cube function on the calculator, simply multiply 948 three times manually.

Step 5: The calculator will display 851,841,792.

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

• Volume of a Cube: The space inside a cube, calculated using the formula V = side length³.

• Cube Root: The number that, when multiplied by itself three times, gives the original number. For example, the cube root of 27 is 3, as 3 × 3 × 3 = 27.
