sodium has a body-centered cubic structure with a unit cell that is 430 picometers wide. estimate the radius of a sodium atom. please help me, I don't know how to get the solution. THank you

• geometry -

for a cube u could use Pythagorean a square plus b square equal c square were a and b are equal and they both equal to 430 pm. and the answer u get is 4 radii and you want one radii so divide it by 4.
