I didn't have a good experience with this because I was not taught with the metric system. Also, for the question with "will the car fit?", I'm sure the correct answer is yes. Through perception, you can see that it will not fit but logically it will if the image is in 3D. If you lay it flat like a sticker, then no. But in real life, it would fit.
It was kind of fun just guessing for me.
