Answer:you can explain more in depth with an 8 sentence paragraph they are both used for explanations or stories
Explanation: With a three sentence paragraph there is very vague sentences not much to go off of if your explaining something, it would be better as a story for kids. With 8 sentences you can go more into depth with what you are explaining and add details to further intrigue the reader. It works well with essays on news or irl things that happened and telling novels.
