Given the almost 50/50 split between right and wrong answers, I suspect most people are taking an educated guess at the answer (I know I did). The emphasis on the word EXACT made me suspect that the answer to this question was going to be no. Thanks for a good learning question.

Excellent question. A good one for Friday - nice and easy.

I don't understand why so many people (184 out of 370 so far) got it wrong.

It must seem blindingly obvious to anyone who has ever had to pack a collection of variously sized objects into a set of equally sized boxes that you can't tell the number of boxes needed from the average object size - and that isn't all that rare a domestic task. When packing to move house (or even for a family holiday) shuffling things between packing crates (or between suitcases) in order to fit more things in is surely a common experience?

People who work with databases should of course know how to do worst case estimates on storage occupancy, so even if they haven't had domestic experience of putting vaious sized pakages into a uniform set of tubs they ought to get this one right. Although it maybe doesn't matter too much - the spread from best case via average case to worst case isn't all that enormous for the criteria given in the problem (unless my mental arithmetic is playing tricks on me).

An even better explanation. Thanks.

Great question. I debated for awhile, completely forgot the way data is stored in pages, and got the answer wrong. But I really enjoyed reading why :)

Ah, correctly answering one of Hugo's questions is a great start to the weekend! I will savor this feeling, as it may very well months until it happens again.

Great question, Hugo.

Thanks, all, for the kind words. I figured a not-too hard yes/no question would make for a nice change of pace. (It being scheduled on a friday is not my doing, though).

The next question in this series (which will be a tough one, I hope) is still being prepared, but I do have another (unrelated) question scheduled for next week - so brace yourselves!
