What is the cube root of 679?

Answer 1

On a scientific calculator you can hit the cubed root button or raise the number by the power of 1/3

Alternatively you can find the number when multiplied by itself 3 times a*a*a= 679

We know that 10*10*10=1000 so the answer has to be less than 10

In fact 8*8*8=512 and 9*9*9=729 so the answer must be between 8 and 9 a course of trial and improvement may be used by cubing decimal numbers between 8 and 9 to your desired degree of accuracy.
