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 795.
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 795 can be written as \(795^3\), which is the exponential form. Or it can also be written in arithmetic form as, 795 \(\times\) 795 \(\times\) 795.
In order to check whether a number is a cube number or not, we can use the following three methods: multiplication method, a factor formula (\(a^3\)), or by using a calculator. These three methods will help in cubing 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 numbers by combining them through repeated multiplication. It is a fundamental operation that forms the basis for more complex mathematical concepts. Step 1: Write down the cube of the given number. \(795^3 = 795 \times 795 \times 795\) Step 2: You get 502,434,375 as the answer. Hence, the cube of 795 is 502,434,375.
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 795 into two parts. Let \(a = 790\) and \(b = 5\), so \(a + b = 795\). Step 2: Now, apply the formula \((a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3\). Step 3: Calculate each term: \(a^3 = 790^3\) \(3a^2b = 3 \times 790^2 \times 5\) \(3ab^2 = 3 \times 790 \times 5^2\) \(b^3 = 5^3\) Step 4: Add all the terms together: \((a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3\) \((790 + 5)^3 = 790^3 + 3 \times 790^2 \times 5 + 3 \times 790 \times 5^2 + 5^3\) \(795^3 = 493,039,000 + 93,525 + 59,250 + 125\) \(795^3 = 502,434,375\) Step 5: Hence, the cube of 795 is 502,434,375.
To find the cube of 795 using a calculator, input the number 795 and use the cube function (if available) or multiply 795 \(\times\) 795 \(\times\) 795. This operation calculates the value of \(795^3\), resulting in 502,434,375. It’s a quick way to determine the cube without manual computation. Step 1: Ensure the calculator is functioning properly. Step 2: Enter 795. Step 3: If the calculator has a cube function, press it to calculate \(795^3\). Step 4: If there is no cube function on the calculator, simply multiply 795 three times manually. Step 5: The calculator will display 502,434,375.
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 might occur during the process of cubing a number. Let us take a look at five of the major mistakes that people might make:
What is the cube and cube root of 795?
The cube of 795 is 502,434,375, and the cube root of 795 is approximately 9.283.
First, let’s find the cube of 795. We know that the cube of a number is \(x^3 = y\), where \(x\) is the given number, and \(y\) is the cubed value of that number. So, we get \(795^3 = 502,434,375\). Next, we must find the cube root of 795. We know that the cube root of a number ‘x’ is \(\sqrt[3]{x} = y\), where ‘x’ is the given number, and ‘y’ is the cube root value of the number. So, we get \(\sqrt[3]{795} \approx 9.283\). Hence, the cube of 795 is 502,434,375, and the cube root of 795 is approximately 9.283.
If the side length of the cube is 795 cm, what is the volume?
The volume is 502,434,375 cm\(^3\).
Use the volume formula for a cube \(V = \text{Side}^3\). Substitute 795 for the side length: \(V = 795^3 = 502,434,375\) cm\(^3\).
How much larger is \(795^3\) than \(790^3\)?
\(795^3 - 790^3 = 9,061,875\).
First, find the cube of 795, which is 502,434,375. Next, find the cube of 790, which is 493,372,500. Now, find the difference between them using the subtraction method: 502,434,375 - 493,372,500 = 9,061,875. Therefore, \(795^3\) is 9,061,875 larger than \(790^3\).
If a cube with a side length of 795 cm is compared to a cube with a side length of 5 cm, how much larger is the volume of the larger cube?
The volume of the cube with a side length of 795 cm is 502,434,375 cm\(^3\).
To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object). Cubing 795 means multiplying 795 by itself three times: 795 \(\times\) 795 = 632,025, and 632,025 \(\times\) 795 = 502,434,375. 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 502,434,375 cm\(^3\).
Estimate the cube of 794.9 using the cube of 795.
The cube of 794.9 is approximately 502,434,375.
First, identify the cube of 795. The cube of 795 is \(795^3 = 502,434,375\). Since 794.9 is only a tiny bit less than 795, the cube of 794.9 will be almost the same as the cube of 795. The cube of 794.9 is approximately 502,434,375 because the difference between 794.9 and 795 is very small. So, we can approximate the value as 502,434,375.
Binomial Formula: 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: 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. Cube Root: The number that, when multiplied by itself three times, gives the original number. For example, the cube root of 27 is 3. Perfect Cube: A number that can be expressed as the cube of an integer. For example, 27 is a perfect cube because it can be written as \(3^3\).
