I dont remember off the top of my head what the formula is but I do know that
volume and temperature are directly proportional therefore, since there is an increase in temperature there is going to be an increase in volume. I solved it by doing the following steps:
200 x
------ = ------
60 180
60x = 36,000
x = 36,000/60
x = 600 cm^3
hope this helps and have a great day :)
