4.6

Explanation:

The solution to x3=95 is x=395

So we just need to approximate 395

We know that 64<95<125, which means 4<x<5

Although 95 is about half way between 64 and 125, since x3 grows faster as x increases, we can pick a number a little closer to 5 than 4.

I picked the number 4.6 as an estimate.

To see how accurate this is, we can plug this into a calculator, and we get x4.56, so we were off by approximately 0.04
