Please, help I don't understand vectors T.T
1. In the prism, assume all dimensions have different lengths, state the following:
a) state 3 equal vectors to DC⃗
b) state 4 opposite vectors to BC⃗

Here is the prism below,

Steve,
I can only assume that while the perpendicular lengths are all different, the faces are parallel?
In that case
AB=DC=EF=HG
opposite to BC would be equal to CB:
CB=DA=HE=GF
since these are vectors, and not just edge lengths, you need to be sure to indicate the direction correctly.
