Richard,
Remember that the actual length of film allows for 36 frames +
leading and trailing portions of film (probably the equivalent to 5 to 6 extra
frames). In addition, the width of the film is not 24mm but 35mm and there are
2mm separating each frame, also. All that, minus the area for the sprocket
holes. So w/o accounting for the trailing and leading portions of film and the
sprocket holes, the area would be:
35 x 38 x 36 = 47,880 mm2
