It looks like your message got cut off. Here's what I understand so far: Harsha made a wind chime using a frame and metal rods. She punched 8 holes in the frame, each 2 cm apart, and then hung... Could you please provide the rest of the details or specify what you need help with? For example, are you asking about the length of the frame, the total distance between the holes, or something else related to the wind chime?
