Cube of 316

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 316 can be written as (316³), which is the exponential form. Or it can also be written in arithmetic form as, 316 × 316 × 316.

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 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. 316³ = 316 x 316 x  316 

Step 2: You get 31,623,936 as the answer. Hence, the cube of 316 is 31,623,936.

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 316 into two parts, as 300 and 16. Let (a = 300) and (b = 16), so (a + b = 316).

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

Step 3: Calculate each term - (a³ = 300³) 

(3a²b = 3 x 300² x 16) 

(3ab² = 3 x 300 x 16²) 

(b³ = 16³)

Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³

(300 + 16)³ = 300³ + 3 x 300² x 16 + 3 x 300 x 16² + 16³

316³ = 27,000,000 + 4,320,000 + 230,400 + 4,096

316³ = 31,623,936

Step 5: Hence, the cube of 316 is 31,623,936.

To find the cube of 316 using a calculator, input the number 316 and use the cube function (if available) or multiply 316 × 316 × 316. This operation calculates the value of (316³), resulting in 31,623,936. It’s a quick way to determine the cube without manual computation.

Step 1: Ensure the calculator is functioning properly.

Step 2: Press 3 followed by 1 and 6.

Step 3: If the calculator has a cube function, press it to calculate (316³).

Step 4: If there is no cube function on the calculator, simply multiply 316 three times manually.

Step 5: The calculator will display 31,623,936.

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: 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, which equals 8.

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

• Volume of a Cube: The amount of space enclosed within a cube, calculated as the cube of the side length.
