[tex]\int \int (x,y,z) \times (x,y,z) \times (x,y,z)[/tex]

[tex]\int_{L1} \int_{L2} (dl1,0,0) \times (dl2,0,0) \times (0,-1,0)[/tex]

What would be correct syntax to evaluate this double integral?

I tried these, but they produce wrong result:

try #1:integral[{l1,0,0} cross {l2,0,0} cross {0,-1,0}, {l1,0,1}, {l2,0,1}]

try #2:integral[l1,0,1] integral[l2,0,1] {l1,0,0} cross {l2,0,0} cross {0,-1,0}
