A cube root of a number is a value, when it is multiplied by itself three times, gives the original number. Imagine you have a cube (box) with a known volume. The cube root helps us determine the length of one side of the box.
The cube root of 300 is the number which, when multiplied three times, we get a number that is equal to 300. Let’s explore some steps and methods to calculate the cube root of 300.
The cube root of 300: ∛300 = 6.694
The exponential form of the cube root of 300: 3001/3
The radical form of the cube root of 300: ∛300
To find the cube root of 300, we use the following methods:
We use the below formula to find the cube root using Halley’s Method;
∛a≅ x((x3+2a) / (2x3+a))
In the formula;
a = given number, 300
x = an approximate number close to the cube root of the number, 300: 63= 216
Let’s apply the formula and find the Cube Root:
A = 300, for the approximate method we choose, x = 6, it is the nearest cube (63= 216).
Now apply the formula;
∛a ≅ x((x3+2a) / (2x3+a))
∛300 ≅ 6((63+2 × 300) / (2 × 63+300)) = 6.694
Hence, the approximate cube of 300 ≅ 6.694
While learning about cube roots, children making mistakes is common, so to avoid a few mistakes that are likely to happen, below are a few mistakes and how to avoid these:
If y = ∛300​, find y²approximately.
y = ∛300
∛300 = 6.694
Therefore, y=6.69433
y2 = 44.81405414
Squaring y = 6.694 gives y2 = 6.672 = 44.81405414
Find ∛300 + 10 approximately.
∛300 = 6.69433
6.694+10=16.694
Adding 10 to ∛300​ gives 16.67.
Evaluate ∛300²​.
The squaring of 300, 3002 = 90000
Finding the cube root of, 90000
∛90000 = 44.81404
To find the value of ∛3002, we squared the value, and then we found the cube root of it.
Simplify ∛(300×300)​.
∛300 = 6.694
∛(300 × 300) = 44.80
The cube root of 3002 approximates to 44.80.
