A meterstick broke into two pieces. If one piece was 54 cm long how long was the other piece?

If the original meterstick was broken into two pieces, and one piece is 54 cm long, then the other piece would be the total length of the meterstick (100 cm) minus the length of the first piece. Therefore, the length of the other piece would be 100 cm - 54 cm = 46 cm.
