Cube of 863

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 863 can be written as \(863^3\), which is the exponential form. Or it can also be written in arithmetic form as, 863 × 863 × 863.

In order to check whether a number is a cube number or not, we can use the following three methods, such as the multiplication method, a factor formula (\(a^3\)), or by using a calculator. These three methods will help 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 multiplication. It is a fundamental operation that forms the basis for more complex mathematical concepts. Step 1: Write down the cube of the given number. \(863^3 = 863 \times 863 \times 863\) Step 2: You get 643,634,367 as the answer. Hence, the cube of 863 is 643,634,367.

The formula \((a + b)^3\) is a binomial formula for finding the cube of a number. The formula is expanded as \(a^3 + 3a^2b + 3ab^2 + b^3\). Step 1: Split the number 863 into two parts. Let \(a = 860\) and \(b = 3\), so \(a + b = 863\). Step 2: Now, apply the formula \((a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3\). Step 3: Calculate each term \(a^3 = 860^3\) \(3a^2b = 3 \times 860^2 \times 3\) \(3ab^2 = 3 \times 860 \times 3^2\) \(b^3 = 3^3\) Step 4: Add all the terms together: \((a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3\) \((860 + 3)^3 = 860^3 + 3 \times 860^2 \times 3 + 3 \times 860 \times 3^2 + 3^3\) \(863^3 = 636056000 + 664860 + 23220 + 27\) \(863^3 = 643634367\) Step 5: Hence, the cube of 863 is 643,634,367.

To find the cube of 863 using a calculator, input the number 863 and use the cube function (if available) or multiply 863 × 863 × 863. This operation calculates the value of \(863^3\), resulting in 643,634,367. It’s a quick way to determine the cube without manual computation. Step 1: Ensure the calculator is functioning properly. Step 2: Enter 863. Step 3: If the calculator has a cube function, press it to calculate \(863^3\). Step 4: If there is no cube function on the calculator, simply multiply 863 three times manually. Step 5: The calculator will display 643,634,367.

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, \(2^3\) represents 2 × 2 × 2 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 side length raised to the third power.
