$vec A X vecB=36hat i+19 hat j+4 hat k$

Explanation:

$vec A=A_x* hat i+A_j* hat j+A_k* hat k$
$vec B=B_x* hat i+B_j* hat j+B_k*hat k$
$"cross product of two vector is determined by:"$
$vec A X vec B=hat i(A_y*B_z-A_z*B_y)- hat j(A_x*B_z-A_z*B_x)+hat k(A_x*B_y-A_y*B_x)$
$vec A X vec B=hat i(4+32)-hat j(-3-16)+hat k(12-8)$
$vec A X vecB=36hat i+19 hat j+4 hat k$
