Cube Root of 300763
A number we multiply by itself three times to get the original number is its cube root. It has various uses in real life, such as finding the volume of cube-shaped objects and designing structures. We will now find the cube root of 300763 and explain the methods used.
What is the Cube Root of 300763?
We have learned the definition of the cube root. Now, let’s learn how it is represented using a symbol and exponent. The symbol we use to express the cube root is the radical sign (∛), and the exponent we use is ⅓.
In exponential form, ∛300763 is written as 300763(1/3). The cube root is just the opposite operation of finding the cube of a number. For example: Assume ‘y’ as the cube root of 300763, then y³ can be 300763. Since the cube root of 300763 is not an exact value, we can write it as approximately 67.287.
Finding the Cube Root of 300763
Finding the cube root of a number is to identify the number that must be multiplied three times resulting in the target number. Now, we will go through the different ways to find the cube root of 300763. The common methods we follow to find the cube root are given below:
- Prime factorization method
- Approximation method
- Subtraction method
- Halley’s method
To find the cube root of a non-perfect cube number, we often follow Halley’s method. Since 300763 is not a perfect cube, we use Halley’s method.
Cube Root of 300763 by Halley’s method
Let's find the cube root of 300763 using Halley’s method.
The formula is ∛a ≅ x((x³ + 2a) / (2x³ + a))
where: a = the number for which the cube root is being calculated
x = the nearest perfect cube
Substituting, a = 300763;
x = 67
∛a ≅ 67((67³ + 2 × 300763) / (2 × 67³ + 300763))
∛300763 ≅ 67.287
The cube root of 300763 is approximately 67.287.
Common Mistakes and How to Avoid Them in the Cube Root of 300763
Finding the perfect cube of a number without any errors can be a difficult task for students. This happens for many reasons. Here are a few mistakes students commonly make and ways to avoid them:
Mistake 1
Trying to find perfect cube roots for non-perfect cube numbers.
Children often try to calculate an exact whole number for the cube root of numbers like 300763, which are not perfect cubes.
For example: They might assume they would get an exact whole number like they do for 27 (since ∛27 = 3). To avoid this error, memorize that some numbers don't have a perfect cube root, and the cube root of 300763 is approximately 67.287.
Cube Root of 300763 Examples:
Problem 1
Imagine you have a cube-shaped storage container that has a total volume of 300763 cubic centimeters. Find the length of one side of the container equal to its cube root.
Side of the cube = ∛300763 ≈ 67.287 units
Explanation
To find the side of the cube, we need to find the cube root of the given volume. Therefore, the side length of the cube is approximately 67.287 units.
Problem 2
A factory produces 300763 cubic meters of material. Calculate the amount of material left after using 100000 cubic meters.
The amount of material left is 200763 cubic meters.
Explanation
To find the remaining material, we need to subtract the used material from the total amount: 300763 - 100000 = 200763 cubic meters.
Problem 3
A tank holds 300763 cubic meters of water. Another tank holds a volume of 150000 cubic meters. What would be the total volume if the tanks are combined?
The total volume of the combined tanks is 450763 cubic meters.
Explanation
Let’s add the volume of both tanks: 300763 + 150000 = 450763 cubic meters.
Problem 4
When the cube root of 300763 is multiplied by 3, calculate the resultant value. How will this affect the cube of the new value?
3 × 67.287 ≈ 201.861 The cube of 201.861 ≈ 8,224,497.8
Explanation
When we multiply the cube root of 300763 by 3, it results in a significant increase in the volume because the cube increases exponentially.
Problem 5
Find ∛(150000 + 150000).
∛(150000 + 150000) = ∛300000 ≈ 67.079
Explanation
As shown in the question ∛(150000 + 150000), we can simplify that by adding them.
So, 150000 + 150000 = 300000.
Then we use this step: ∛300000 ≈ 67.079 to get the answer.
