When a number is multiplied by itself thrice, the resultant number is called the cube of a number. Cubing is used when comparing sizes of objects or things with cubic measurements. In this topic, we shall learn about cubes of 338.
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 338 can be written as \(338^3\), which is the exponential form. Or it can also be written in arithmetic form as, 338 × 338 × 338.
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
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. \(338^3 = 338 \times 338 \times 338\) Step 2: You get 38,637,272 as the answer. Hence, the cube of 338 is 38,637,272.
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 338 into two parts. Let \(a = 330\) and \(b = 8\), so \(a + b = 338\) Step 2: Now, apply the formula \((a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3\) Step 3: Calculate each term \(a^3 = 330^3\) \(3a^2b = 3 \times 330^2 \times 8\) \(3ab^2 = 3 \times 330 \times 8^2\) \(b^3 = 8^3\) Step 4: Add all the terms together: \((a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3\) \((330 + 8)^3 = 330^3 + 3 \times 330^2 \times 8 + 3 \times 330 \times 8^2 + 8^3\) \(338^3 = 35,937,000 + 261,360 + 63,360 + 512\) \(338^3 = 38,637,272\) Step 5: Hence, the cube of 338 is 38,637,272.
To find the cube of 338 using a calculator, input the number 338 and use the cube function (if available) or multiply 338 × 338 × 338. This operation calculates the value of \(338^3\), resulting in 38,637,272. 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 3 and 8 Step 3: If the calculator has a cube function, press it to calculate \(338^3\). Step 4: If there is no cube function on the calculator, simply multiply 338 three times manually. Step 5: The calculator will display 38,637,272.
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 338?
The cube of 338 is 38,637,272 and the cube root of 338 is approximately 7.003.
First, let’s find the cube of 338. We know that the 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 \(338^3 = 38,637,272\) Next, we must find the cube root of 338 We know that the 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 \(\sqrt[3]{338} \approx 7.003\) Hence the cube of 338 is 38,637,272 and the cube root of 338 is approximately 7.003.
If the side length of the cube is 338 cm, what is the volume?
The volume is 38,637,272 cm³.
Use the volume formula for a cube \(V = \text{Side}^3\). Substitute 338 for the side length: \(V = 338^3 = 38,637,272 \text{ cm}^3\).
How much larger is \(338^3\) than \(330^3\)?
\(338^3 - 330^3 = 2,700,592\).
First, find the cube of \(338^3\), that is 38,637,272 Next, find the cube of \(330^3\), which is 35,937,000 Now, find the difference between them using the subtraction method. 38,637,272 - 35,937,000 = 2,700,592 Therefore, \(338^3\) is 2,700,592 larger than \(330^3\).
If a cube with a side length of 338 cm is compared to a cube with a side length of 8 cm, how much larger is the volume of the larger cube?
The volume of the cube with a side length of 338 cm is 38,637,272 cm³.
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object). Cubing 338 means multiplying 338 by itself three times: 338 × 338 = 114,244, and 114,244 × 338 = 38,637,272. The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube. Therefore, the volume of the cube is 38,637,272 cm³.
Estimate the cube of 337.9 using the cube of 338.
The cube of 337.9 is approximately 38,637,272.
First, identify the cube of 338, The cube of 338 is \(338^3 = 38,637,272\). Since 337.9 is only a tiny bit less than 338, the cube of 337.9 will be almost the same as the cube of 338. The cube of 337.9 is approximately 38,637,272 because the difference between 337.9 and 338 is very small. So, we can approximate the value as 38,637,272.
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 \(2 \times 2 \times 2\) equals to 8. Perfect Cube: A number that can be expressed as the cube of an integer is called a perfect cube. Volume of a Cube: The amount of space occupied by a cube, calculated by multiplying the side length by itself three times.
