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 512000 and explain the methods used.
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, ∛512000 is written as 512000(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 512000, then y3 can be 512000. The cube root of 512000 is an exact value, which is 80.
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 512000. The common methods we follow to find the cube root are given below:
For 512000, we can use the prime factorization method because it is a perfect cube.
Let's find the cube root of 512000 using the prime factorization method.
The prime factorization of 512000 is: 512000 = 29 × 53
Now, to find the cube root, we take the cube root of each factor: ∛(29 × 53) = 2(9/3) × 5(3/3) = 23 × 51 = 8 × 5 = 40
The cube root of 512000 is 80.
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 the students commonly make and the ways to avoid them:
Imagine you have a cube-shaped storage container with a total volume of 512000 cubic centimeters. Find the length of one side of the container equal to its cube root.
Side of the cube = ∛512000 = 80 units
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 80 units.
A warehouse has 512000 cubic meters of storage space. Calculate the amount of space left after using 320000 cubic meters.
The amount of space left is 192000 cubic meters.
To find the remaining space, we need to subtract the used space from the total amount: 512000 - 320000 = 192000 cubic meters.
A tank holds 512000 cubic meters of water. Another tank holds a volume of 88000 cubic meters. What would be the total volume if the tanks are combined?
The total volume of the combined tanks is 600000 cubic meters.
Explanation: Let’s add the volume of both tanks: 512000 + 88000 = 600000 cubic meters.
When the cube root of 512000 is multiplied by 2, calculate the resultant value. How will this affect the cube of the new value?
2 × 80 = 160 The cube of 160 = 4096000
When we multiply the cube root of 512000 by 2, it results in a significant increase in the volume because the cube increases exponentially.
Find ∛(256000 + 256000).
∛(256000 + 256000) = ∛512000 = 80
As shown in the question ∛(256000 + 256000), we can simplify that by adding them.
So, 256000 + 256000 = 512000.
Then we use this step: ∛512000 = 80 to get the answer.
