If each frame of a motion picture film is 35 cm high, and 24 frames go by in a second, estimate how many frames are needed to show a two hour long movie. Question 1 options: 1) 1400 2) 25 000 3) 50 000 4) 170 000 5) This cannot be determined without knowing how many reels were used.

24 frame per second X 3600 seconds per hour X 2 hoursX = 172800

Ok, so why did they tell the height in there?

They (we!) do it for a good reason. One of the important things to figure in science is what is information is germane to the problem, what information is relevant. For what it's worth, this is also very true in business, so it's good training for the life in the real world, as well as being good science.
