As an expert in video and animation production, I can tell you that the number of blocks in a 6-second strip depends on the frame rate of the video or animation. A "block" in this context typically refers to a single frame of video.

For standard video, the frame rate is often 24 frames per second (fps). If we assume that's the case, then a 6-second strip would contain:
24 frames/second * 6 seconds = 144 frames

However, if the frame rate is different, the number of blocks (frames) would be different as well. For example, at 30 fps, a 6-second strip would have:
30 frames/second * 6 seconds = 180 frames

So, the number of blocks in a 6-second strip is directly related to the frame rate of the video.

Each small square represents 0.04 seconds of time. 5 small squares equal 0.20 seconds of time. When you are trying to calculate the heart rate with the six second rule, you must count out enough LARGE squares to equal 6 seconds. Therefore, 30 large squares would equal 6 seconds.read more >>
