What is the cube root of 64 (∛64)? How do you estimate the cube root of 64? How do you calculate the approximate cube root of 64 without a calculator? How do you find the cube root of 64 with a calculator?

First things first! The cube root of 64 is the number that when multiplied by itself twice equals 64. In other words, the cube root of 64 is the A in the following notations: A × A × A or A³.

Here is how to calculate the approximate cube root of 64 without a calculator by using a cube root estimate formula.

We start by finding the perfect cube that is closest to 64. Looking at the list of perfect cubes at the bottom of this page, we can see that 64 is the closest perfect cube to 64.

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 = 64 and c = 64 into our cube root formula, we get the approximate cube root of 64 as follows:

∛n = ∛c + ((n - c) ÷ ((∛c)² × 3))

∛64 = ∛64 + ((64 - 64) ÷ ((∛64)² × 3))

∛64 = 4 + (0 ÷ 48)

∛64 = 4

To get the cube root of 64 using a calculator, we can press 64, followed by the [∛] button, to get this answer:

∛64 = 4
