What is the cube root of 43 (∛43)? How do you estimate the cube root of 43? How do you calculate the approximate cube root of 43 without a calculator? How do you find the cube root of 43 with a calculator?

First things first! The cube root of 43 is the number that when multiplied by itself twice equals 43. In other words, the cube root of 43 is the A in the following notations: A × A × A or A³.

Here is how to calculate the approximate cube root of 43 without a calculator by using a cube root estimate formula.

We start by finding the perfect cube that is closest to 43. Looking at the list of perfect cubes at the bottom of this page, we can see that 27 is the closest perfect cube to 43.

The formula to estimate the cube root of any number (n) using the closest perfect cube (c) is as follows:

∛n = ∛c + ((n - c) ÷ ((∛c)² × 3))

When we enter n = 43 and c = 27 into our cube root formula, we get the approximate cube root of 43 as follows:

∛n = ∛c + ((n - c) ÷ ((∛c)² × 3))

∛43 ≈ ∛27 + ((43 - 27) ÷ ((∛27)² × 3))

∛43 ≈ 3 + (16 ÷ 27)

∛43 ≈ 3.5

To get a more exact answer to the cube root of 43 using a calculator, we can press 43, followed by the [∛] button, to get this answer:

∛43 ≈ 3.50339806038672
