There is a piece of wood, and it takes 1 minute for sawing 1 meter, and it takes ***6 minutes to finish sawing. How long is this piece of wood? (Assuming that the length of wood is an integer)

Answer: It takes 1 minute for each sawing, and * * * sawed for 6 minutes, so it was sawed for 6 times. Saw 6 times * * * has 7 segments (this student can understand why it is 7 segments through physical simulation), and each segment is 1 meter, so it is 7 meters long.
