I believe it is B. I could be wrong but I am hoping that you get it right
Does 14cm2 mean 14cm squared? Because if it does then each face is 196cm and thats D but then u have to times it by 6 which isnt one of the answers. If 14cm2 is 14x2 then thats 28cm area for each face, so the whole cube is 28x6.
