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 determining the side length of cube-shaped objects and understanding geometric properties. We will now find the cube root of 603 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, ∛603 is written as 603(1/3). The cube root is just the opposite operation of finding the cube of a number. For example: Assume ‘y’ is the cube root of 603, then y3 can be 603. Since the cube root of 603 is not an exact value, we can write it as approximately 8.4149.
Finding the cube root of a number involves identifying 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 603. The common methods we follow to find the cube root are given below: -
To find the cube root of a non-perfect cube, we often follow Halley’s method. Since 603 is not a perfect cube, we use Halley’s method.
Let's find the cube root of 603 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 = 603; x = 8
∛a ≅ 8((83 + 2 × 603) / (2 × 83 + 603))
∛603 ≅ 8((512 + 2 × 603) / (2 × 512 + 603))
∛603 ≅ 8.4149
The cube root of 603 is approximately 8.4149.
Calculating the cube root 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:
Imagine you have a cube-shaped container that has a total volume of 603 cubic centimeters. Find the length of one side of the cube, equal to its cube root.
Side of the cube = ∛603 ≈ 8.41 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 approximately 8.41 units.
A company manufactures 603 cubic meters of material. Calculate the amount of material left after using 100 cubic meters.
The amount of material left is 503 cubic meters.
To find the remaining material,
subtract the used material from the total amount:
603 - 100 = 503 cubic meters.
A tank holds 603 cubic meters of water. Another tank holds a volume of 50 cubic meters. What would be the total volume if the tanks are combined?
The total volume of the combined tanks is 653 cubic meters.
Let’s add the volume of both tanks:
603 + 50 = 653 cubic meters.
When the cube root of 603 is multiplied by 2, calculate the resultant value. How will this affect the cube of the new value?
2 × 8.41 ≈ 16.82
The cube of 16.82 ≈ 4,755.36
When we multiply the cube root of 603 by 2, it results in a significant increase in the volume because the cube increases exponentially.
Find ∛(300+303).
∛(300+303) = ∛603 ≈ 8.41
As shown in the question ∛(300+303),
we can simplify that by adding them.
So, 300 + 303 = 603.
Then we use this step: ∛603 ≈ 8.41 to get the answer.
