How Do You Calculate Torque on a Triangular Loop in a Magnetic Field?

[bibo_dvd]

hello guys
iam doing my homework in magnetic fields course
and i found this problem i solved (a) and (b)

by using F=I L x B and the total force on the triangular loop would be zero
but in (c) i tried a lot to find the torque on the loop but i couldn't get the same result
so please help me with this :)
Thx guys :)

Show what you tried. How do you determine the torque on a current carrying loop?
