Cube of 775

Professor Greenline Explaining Math Concepts

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.

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 775ยณ, which is the exponential form. Or it can also be written in arithmetic form as, 775 ร— 775 ร— 775.

How to Calculate the Value of the Cube of 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 (aยณ), 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

By Multiplication Method

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. 775ยณ = 775 ร— 775 ร— 775 Step 2: You get 465,484,375 as the answer. Hence, the cube of 775 is 465,484,375.

Using a Formula (aยณ)

The formula (a + b)ยณ is a binomial formula for finding the cube of a number. The formula is expanded as aยณ + 3aยฒb + 3abยฒ + bยณ. 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)ยณ = aยณ + 3aยฒb + 3abยฒ + bยณ Step 3: Calculate each term: aยณ = 700ยณ 3aยฒb = 3 ร— 700ยฒ ร— 75 3abยฒ = 3 ร— 700 ร— 75ยฒ bยณ = 75ยณ Step 4: Add all the terms together: (a + b)ยณ = aยณ + 3aยฒb + 3abยฒ + bยณ (700 + 75)ยณ = 700ยณ + 3 ร— 700ยฒ ร— 75 + 3 ร— 700 ร— 75ยฒ + 75ยณ Step 5: Hence, the cube of 775 is 465,484,375.

Using a Calculator

To find the cube of 775 using a calculator, input the number 775 and use the cube function (if available) or multiply 775 ร— 775 ร— 775. This operation calculates the value of 775ยณ, resulting in 465,484,375. Itโ€™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 775ยณ. 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.

Tips and Tricks for the Cube of 775

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.

Common Mistakes to Avoid When Calculating the Cube of 775

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:

Mistake 1

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Incorrect Multiplication

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Kids might multiply the numbers only twice. That is, 775 ร— 775 and not 775 ร— 775 ร— 775. Always remember that 775ยณ = 775 ร— 775 ร— 775.

Mistake 2

Misunderstanding the Cube Formula

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

There is a possibility that kids might be confused between the formulas of square numbers and cube numbers. The square number formula is (a + b)ยฒ and the cube number formula is (a + b)ยณ. Always review the formula for the difference between squaring and cubing.

Mistake 3

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Calculator Misuse

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Kids might press the wrong buttons, such as using the square (xยฒ) function instead of the cube (xยณ) function, or skipping steps in manual multiplication. Always double-check your inputs on the calculator, and if it lacks a cube function, perform the multiplication in steps.

Mistake 4

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Misplacing Zeros

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Misplacing zeros during manual multiplication leads to incorrect results like 4,654,843 instead of 465,484,375. For this, kids should always double-check their answers.

Mistake 5

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Ignoring the Binomial Formula

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Kids might attempt to split the 775 into 700 + 75 but not apply the correct binomial expansion. In order to avoid this, carefully calculate each term step-by-step during the application of the formula.

Problem 1

What is the cube and cube root of 775?

Ray, the Boy Character from BrightChamps Saying "Letโ€™s Begin"
Okay, lets begin

The cube of 775 is 465,484,375 and the cube root of 775 is approximately 9.279.

Explanation

First, letโ€™s find the cube of 775. We know that the cube of a number is such that xยณ = y, where x is the given number, and y is the cubed value of that number. So, we get 775ยณ = 465,484,375. Next, we must find the cube root of 775. We know that the cube root of a number โ€˜xโ€™ is such that โˆ›x = y, where โ€˜xโ€™ is the given number, and y is the cube root value of the number. So, we get โˆ›775 โ‰ˆ 9.279. Hence, the cube of 775 is 465,484,375 and the cube root of 775 is approximately 9.279.

Problem 3

How much larger is 775ยณ than 700ยณ?

Ray, the Boy Character from BrightChamps Saying "Letโ€™s Begin"
Okay, lets begin

775ยณ โ€“ 700ยณ = 285,984,375.

Explanation

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 โ€“ 343,000,000 = 122,484,375. Therefore, 775ยณ is 122,484,375 larger than 700ยณ.

Problem 4

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?

Ray, the Boy Character from BrightChamps Saying "Letโ€™s Begin"
Okay, lets begin

The volume of the cube with a side length of 775 cm is 465,484,375 cmยณ.

Explanation

To find its volume, we multiply the side length by itself three times (since itโ€™s a 3-dimensional object). Cubing 775 means multiplying 775 by itself three times: 775 ร— 775 = 600,625, and then 600,625 ร— 775 = 465,484,375. The unit of volume is cubic centimeters (cmยณ) because we are calculating the space inside the cube. Therefore, the volume of the cube is 465,484,375 cmยณ.

Problem 5

Estimate the cube of 774.9 using the cube of 775.

Ray, the Boy Character from BrightChamps Saying "Letโ€™s Begin"
Okay, lets begin

The cube of 774.9 is approximately 465,484,375.

Explanation

First, identify the cube of 775, The cube of 775 is 775ยณ = 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.
