Its formula is ∛a ≈ x ((x3 + 2a)/(2x3 + a))
where,
a = number whose cube root is being calculated
x = integer guess of its cube root.
Here a = 11
Let us assume x as 2
[∵ 23 = 8 and 8 is the nearest perfect cube that is less than 11]
⇒ x = 2
Therefore,
∛11 = 2 (23 + 2 × 11)/(2 × 23 + 11)) = 2.22
⇒ ∛11 ≈ 2.22
Therefore, the cube root of 11 is 2.22 approximately.
