I need major help with a trihybrid cross!!?!?!?

Okay so i have to cross
a heterozygous long lash+ curly haired+ narrow nose+woman
and a heterozygous long lash broad nose man with straigh hair

This is my KEY:
L=long lashes
l= short lashes
C=curly hair
c= straight hair
B=broad nose
b=narrow nose

Now by question is how do you FOIL for a trihybrid cross? do you even use FOIL? i have no idea because this is for extra credit for bio, and my teacher said we had to figure it out
so someone pleaseee help me to find out how i figure out what goes on the outside if of the box
in an easy wayy to so i can understand im a freshman in HS if that helps.

thanks in advance
