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 389017 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, ∛389017 is written as 389017(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 389017, then y3 can be 389017. Since the cube root of 389017 is not an exact whole number, we can write it as approximately 73.1677.
Finding the cube root of a number is 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 389017. The common methods we follow to find the cube root are given below:
To find the cube root of a non-perfect cube number, we often follow Halley’s method. Since 389017 is not a perfect cube, we use Halley’s method.
Let's find the cube root of 389017 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 = 389017;
x = 73
∛a ≅ 73((733 + 2 × 389017) / (2 × 733 + 389017))
∛389017 ≅ 73((389017 + 778034) / (778034 + 389017))
∛389017 ≅ 73.1677
The cube root of 389017 is approximately 73.1677.
Imagine you have a cube-shaped storage box that has a total volume of 389017 cubic centimeters. Find the length of one side of the box equal to its cube root.
A company manufactures 389017 cubic meters of material. Calculate the amount of material left after using 150000 cubic meters.
A water tank holds 389017 cubic meters of water. Another tank holds a volume of 10000 cubic meters. What would be the total volume if the tanks are combined?
When the cube root of 389017 is multiplied by 3, calculate the resultant value. How will this affect the cube of the new value?
