What is the cube root of 270 (∛270)? How do you estimate the cube root of 270? How do you calculate the approximate cube root of 270 without a calculator? How do you find the cube root of 270 with a calculator?

First things first! The cube root of 270 is the number that when multiplied by itself twice equals 270. In other words, the cube root of 270 is the A in the following notations: A × A × A or A³.

Here is how to calculate the approximate cube root of 270 without a calculator by using a cube root estimate formula.

We start by finding the perfect cube that is closest to 270. Looking at the list of perfect cubes at the bottom of this page, we can see that 216 is the closest perfect cube to 270.

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 = 270 and c = 216 into our cube root formula, we get the approximate cube root of 270 as follows:

∛n = ∛c + ((n - c) ÷ ((∛c)² × 3))

∛270 ≈ ∛216 + ((270 - 216) ÷ ((∛216)² × 3))

∛270 ≈ 6 + (54 ÷ 108)

∛270 ≈ 6.5

To get a more exact answer to the cube root of 270 using a calculator, we can press 270, followed by the [∛] button, to get this answer:

∛270 ≈ 6.46330407009565
