Cube of 340

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 340.

Cube of 340

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 340 can be written as \(340^3\), which is the exponential form. Or it can also be written in arithmetic form as, \(340 \times 340 \times 340\).

How to Calculate the Value of Cube of 340

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 (\(a^3\)), 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

Professor Greenline from BrightChamps

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. \(340^3 = 340 \times 340 \times 340\) Step 2: You get 39,304,000 as the answer. Hence, the cube of 340 is 39,304,000.

Using a Formula (\(a^3\))

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 340 into two parts, as 300 and 40. Let \(a = 300\) and \(b = 40\), so \(a + b = 340\) Step 2: Now, apply the formula \((a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3\) Step 3: Calculate each term \(a^3= 300^3\) \(3a^2b = 3 \times 300^2 \times 40\) \(3ab^2 = 3 \times 300 \times 40^2\) \(b^3 = 40^3\) Step 4: Add all the terms together: \((a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3\) \((300 + 40)^3 = 300^3 + 3 \times 300^2 \times 40 + 3 \times 300 \times 40^2 + 40^3\) \(340^3 = 27,000,000 + 10,800,000 + 1,440,000 + 64,000\) \(340^3 = 39,304,000\) Step 5: Hence, the cube of 340 is 39,304,000.

Professor Greenline from BrightChamps

Using a Calculator

To find the cube of 340 using a calculator, input the number 340 and use the cube function (if available) or multiply \(340 \times 340 \times 340\). This operation calculates the value of \(340^3\), resulting in 39,304,000. 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 4 and 0 Step 3: If the calculator has a cube function, press it to calculate \(340^3\). Step 4: If there is no cube function on the calculator, simply multiply 340 three times manually. Step 5: The calculator will display 39,304,000.

Tips and Tricks for the Cube of 340

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.

Problem 1

What is the cube and cube root of 340?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The cube of 340 is 39,304,000 and the cube root of 340 is approximately 6.957.

Explanation

First, let’s find the cube of 340. We know that cube of a number, such that \(x^3 = y\) Where \(x\) is the given number, and \(y\) is the cubed value of that number So, we get \(340^3 = 39,304,000\) Next, we must find the cube root of 340 We know that cube root of a number \(x\), such that \(\sqrt[3]{x} = y\) Where \(x\) is the given number, and \(y\) is the cube root value of the number So, we get \(\sqrt[3]{340} \approx 6.957\) Hence the cube of 340 is 39,304,000 and the cube root of 340 is approximately 6.957.

Problem 2

If the side length of the cube is 340 cm, what is the volume?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The volume is 39,304,000 cm\(^3\).

Explanation

Use the volume formula for a cube \(V = \text{Side}^3\). Substitute 340 for the side length: \(V = 340^3 = 39,304,000 \text{ cm}^3\).

Problem 3

How much larger is \(340^3\) than \(300^3\)?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

\(340^3 - 300^3 = 12,304,000\).

Explanation

First find the cube of \(340^3\), that is 39,304,000 Next, find the cube of \(300^3\), which is 27,000,000 Now, find the difference between them using the subtraction method. 39,304,000 - 27,000,000 = 12,304,000 Therefore, \(340^3\) is 12,304,000 larger than \(300^3\).

Problem 4

If a cube with a side length of 340 cm is compared to a cube with a side length of 40 cm, how much larger is the volume of the larger cube?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The volume of the cube with a side length of 340 cm is 39,304,000 cm\(^3\).

Explanation

To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object). Cubing 340 means multiplying 340 by itself three times: 340 \(\times\) 340 = 115,600, and then 115,600 \(\times\) 340 = 39,304,000. The unit of volume is cubic centimeters (cm\(^3\)), because we are calculating the space inside the cube. Therefore, the volume of the cube is 39,304,000 cm\(^3\).

Problem 5

Estimate the cube 339.9 using the cube 340.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The cube of 339.9 is approximately 39,304,000.

Explanation

First, identify the cube of 340, The cube of 340 is \(340^3 = 39,304,000\). Since 339.9 is only a tiny bit less than 340, the cube of 339.9 will be almost the same as the cube of 340. The cube of 339.9 is approximately 39,304,000 because the difference between 339.9 and 340 is very small. So, we can approximate the value as 39,304,000.
