You would need to show us what you think it would be, how you would calculate it ..?members are very reluctant to answer coursework or similar questions without some initial input. Harsh but true and fair.

Welcome to the forum...

If you want to get some constructive help its best to show what you think the answer should be first..

Including how you think you have calculated the answer...

As just spoon feeding answers to people is of very little help to anyone..

The answer is obviously 42, because according to sources like Hitch Guide to the Universe that is the answer to everything.

If however you want a sensible answer then follow the advice above.
