John needs to cut three strips of wood, 25.5 cm, 15.3 cm, and 9.25 cm long. he has a strip that is 72 cm long. how long will the leftover piece be after he cuts what he needs?

He will have a 21.95 long strip of wood. How you can double check is by doing this:

You can subtract 25.5 from 72, to get 46.5. Next, subtract 15.3 from 43.5, to get 31.2. Finally, subtract 9.25 from 31.2 to get your final 21.95.

Hope this helps, and good luck!!

Bis the answer! hope this
