Can I say "a 5 cents at cubic-inch" instead?

No, it would not be grammatically correct to say "a 5 cents at cubic-inch" here. This is because "at" must come before "5 cents" since it referring to where the price is "at", and it is "at 5 cents". "A" in this sentence must come before "cubic-inch" because "a" has a meaning of "per" or "for every" in this context. Ex: I exercise once a week. Ex: They cost $50 a kilo.
