When a number is multiplied by itself thrice, the resultant number is called the cube of a number. Cubing is used while comparing sizes of objects or things with cubic measurements. In this topic, we shall learn about the cube of 775.
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 775 can be written as 775³, which is the exponential form. Or it can also be written in arithmetic form as, 775 × 775 × 775.
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 (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. 775³ = 775 × 775 × 775 Step 2: You get 465,484,375 as the answer. Hence, the cube of 775 is 465,484,375.
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 775 into two parts, as 700 and 75. Let a = 700 and b = 75, so a + b = 775 Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³ Step 3: Calculate each term: a³ = 700³ 3a²b = 3 × 700² × 75 3ab² = 3 × 700 × 75² b³ = 75³ Step 4: Add all the terms together: (a + b)³ = a³ + 3a²b + 3ab² + b³ (700 + 75)³ = 700³ + 3 × 700² × 75 + 3 × 700 × 75² + 75³ Step 5: Hence, the cube of 775 is 465,484,375.
To find the cube of 775 using a calculator, input the number 775 and use the cube function (if available) or multiply 775 × 775 × 775. This operation calculates the value of 775³, resulting in 465,484,375. It’s a quick way to determine the cube without manual computation. Step 1: Ensure the calculator is functioning properly. Step 2: Press 7 followed by 7 and 5. Step 3: If the calculator has a cube function, press it to calculate 775³. Step 4: If there is no cube function on the calculator, simply multiply 775 three times manually. Step 5: The calculator will display 465,484,375.
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.
There are some typical errors that kids might make during the process of cubing a number. Let us take a look at five of the major mistakes that kids might make:
What is the cube and cube root of 775?
The cube of 775 is 465,484,375 and the cube root of 775 is approximately 9.279.
First, let’s find the cube of 775. We know that the cube of a number is such that x³ = y, where x is the given number, and y is the cubed value of that number. So, we get 775³ = 465,484,375. Next, we must find the cube root of 775. We know that the cube root of a number ‘x’ is such that ∛x = y, where ‘x’ is the given number, and y is the cube root value of the number. So, we get ∛775 ≈ 9.279. Hence, the cube of 775 is 465,484,375 and the cube root of 775 is approximately 9.279.
If the side length of the cube is 775 cm, what is the volume?
The volume is 465,484,375 cm³.
Use the volume formula for a cube V = Side³. Substitute 775 for the side length: V = 775³ = 465,484,375 cm³.
How much larger is 775³ than 700³?
775³ – 700³ = 285,984,375.
First, find the cube of 775, which is 465,484,375. Next, find the cube of 700, which is 343,000,000. Now, find the difference between them using the subtraction method. 465,484,375 – 343,000,000 = 122,484,375. Therefore, 775³ is 122,484,375 larger than 700³.
If a cube with a side length of 775 cm is compared to a cube with a side length of 75 cm, how much larger is the volume of the larger cube?
The volume of the cube with a side length of 775 cm is 465,484,375 cm³.
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object). Cubing 775 means multiplying 775 by itself three times: 775 × 775 = 600,625, and then 600,625 × 775 = 465,484,375. The unit of volume is cubic centimeters (cm³) because we are calculating the space inside the cube. Therefore, the volume of the cube is 465,484,375 cm³.
Estimate the cube of 774.9 using the cube of 775.
The cube of 774.9 is approximately 465,484,375.
First, identify the cube of 775, The cube of 775 is 775³ = 465,484,375. Since 774.9 is only a tiny bit less than 775, the cube of 774.9 will be almost the same as the cube of 775. The cube of 774.9 is approximately 465,484,375 because the difference between 774.9 and 775 is very small. So, we can approximate the value as 465,484,375.
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 is called a perfect cube. Cube Root: The cube root of a number is a value that, when multiplied by itself three times, gives the original number.
