Let `vec a = a_1 hat i + a_2 hat j+ a_3 hat k;vec b = b_1 hat i+ b_2 hat j+ b_3 hat k ; vec c= c_1hat i + c_2 hat j+ c_3 hat k` be three non-zero vectors such that `vec c` is a unit vector perpendicular to both `vec a & vec b`. If the angle between `vec a and vec b` is `pi/6` , then `|(a_1,b_1,c_1),(a_2,b_2,c_2),(a_3,b_3,c_3)|^2=`
