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 the cube of 676.
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 676 can be written as 6763, which is the exponential form. Or it can also be written in arithmetic form as, \(676 \times 676 \times 676\).
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. \(676^3 = 676 \times 676 \times 676\) Step 2: You get 309,591,056 as the answer. Hence, the cube of 676 is 309,591,056.
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 676 into two parts, as \(a\) and \(b\). Let \(a = 600\) and \(b = 76\), so \(a + b = 676\) Step 2: Now, apply the formula \((a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3\) Step 3: Calculate each term \(a^3 = 600^3\) \(3a^2b = 3 \times 600^2 \times 76\) \(3ab^2 = 3 \times 600 \times 76^2\) \(b^3 = 76^3\) Step 4: Add all the terms together: \((a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3\) \((600 + 76)^3= 600^3 + 3 \times 600^2 \times 76 + 3 \times 600 \times 76^2 + 76^3\) \(676^3 = 216,000,000 + 82,080,000 + 10,368,000 + 438,976\) \(676^3 = 309,591,056\) Step 5: Hence, the cube of 676 is 309,591,056.
To find the cube of 676 using a calculator, input the number 676 and use the cube function (if available) or multiply \(676 \times 676 \times 676\). This operation calculates the value of \(676^3\), resulting in 309,591,056. It’s a quick way to determine the cube without manual computation. Step 1: Ensure the calculator is functioning properly. Step 2: Press 6 followed by 7 and 6 Step 3: If the calculator has a cube function, press it to calculate \(676^3\). Step 4: If there is no cube function on the calculator, simply multiply 676 three times manually. Step 5: The calculator will display 309,591,056.
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 676?
The cube of 676 is 309,591,056 and the cube root of 676 is approximately 8.780.
First, let’s find the cube of 676. 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 \(676^3 = 309,591,056\) Next, we must find the cube root of 676 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 \(\sqrt[3]{676} \approx 8.780\) Hence, the cube of 676 is 309,591,056 and the cube root of 676 is approximately 8.780.
If the side length of the cube is 676 cm, what is the volume?
The volume is 309,591,056 cm³.
Use the volume formula for a cube \(V = \text{Side}^3\). Substitute 676 for the side length: \(V = 676^3 = 309,591,056 \, \text{cm}^3\).
How much larger is \(676^3\) than \(500^3\)?
\(676^3 – 500^3 = 234,591,056\).
First find the cube of \(676^3\), that is 309,591,056 Next, find the cube of \(500^3\), which is 125,000,000 Now, find the difference between them using the subtraction method. 309,591,056 – 125,000,000 = 184,591,056 Therefore, \(676^3\) is 184,591,056 larger than \(500^3\).
If a cube with a side length of 676 cm is compared to a cube with a side length of 100 cm, how much larger is the volume of the larger cube?
The volume of the cube with a side length of 676 cm is 309,591,056 cm³.
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object). Cubing 676 means multiplying 676 by itself three times: 676 \(\times\) 676 = 456,976, and then 456,976 \(\times\) 676 = 309,591,056. The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube. Therefore, the volume of the cube is 309,591,056 cm³.
Estimate the cube of 675 using the cube of 676.
The cube of 675 is approximately 309,591,056.
First, identify the cube of 676, The cube of 676 is \(676^3 = 309,591,056\). Since 675 is only a tiny bit less than 676, the cube of 675 will be almost the same as the cube of 676. The cube of 675 is approximately 309,591,056 because the difference between 675 and 676 is very small. So, we can approximate the value as 309,591,056.
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 8. Perfect Cube: A number that is the cube of an integer. For example, 27 is a perfect cube because it is \(3^3\). Volume of a Cube: This is the amount of space enclosed within a cube, calculated as the cube of the side length of the cube (\(s^3\)).
