cell with an edge length of 362 pm. What is the radius of a Cu atom in pm?

What equation do you use?

you have to think on a side.

Looks like to me four r radius= 1 diagonal

4r=sqrt2* 362pm
solve for r.
it says it's incorrect
To calculate the radius of cooper in face centred cubic unit cell there is a simple formula let a be the edge length then the formula is a/2rootunder2 or a/under root8 then according to question..r equal to 362/2root under 2 hope you understand
