If it's 13.6g per cm^3. then you multiply by the number of cm^3 that you have... ie, 18.
18 x13.6 = 244.8g
---
The density is actually 13.534g/cm^3
So the real answer is 243.612g
But the value you gave is close enough and you should use that in your answer.

just 18 x 13.6g = 244.8g
because you were saying 1 cm^3 weigh 13.6 g

You are told that one cubic centimeter is 13.6 grams -- so 18 CCs would be 18 times that.
18*13.6 = 244.8
