Cube of 875

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 875 can be written as 875³, which is the exponential form. Or it can also be written in arithmetic form as, 875 × 875 × 875.

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 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. 875³ = 875 × 875 × 875 Step 2: You get 669,921,875 as the answer. Hence, the cube of 875 is 669,921,875.

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 875 into two parts. Let a = 800 and b = 75, so a + b = 875 Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³ Step 3: Calculate each term a³ = 800³ 3a²b = 3 × 800² × 75 3ab² = 3 × 800 × 75² b³ = 75³ Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (800 + 75)³ = 800³ + 3 × 800² × 75 + 3 × 800 × 75² + 75³ 875³ = 512,000,000 + 144,000,000 + 135,000,000 + 421,875 875³ = 669,921,875 Step 5: Hence, the cube of 875 is 669,921,875.

To find the cube of 875 using a calculator, input the number 875 and use the cube function (if available) or multiply 875 × 875 × 875. This operation calculates the value of 875³, resulting in 669,921,875. It’s a quick way to determine the cube without manual computation. Step 1: Ensure the calculator is functioning properly. Step 2: Press 8 followed by 7 and then 5 Step 3: If the calculator has a cube function, press it to calculate 875³. Step 4: If there is no cube function on the calculator, simply multiply 875 three times manually. Step 5: The calculator will display 669,921,875.

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. Volume of a Cube: It is the space occupied by a cube, calculated using the formula side³, where 'side' is the length of one side of the cube. Perfect Cube: A number that can be expressed as the cube of an integer. For example, 8 is a perfect cube because it can be expressed as 2³.
