a log that is 50 cm long is cut into 2 pieces one of the pieces is 8 cm shorter than the other one. how long is orginal log and if the original log is cut into equal pieces how long would each piece be

The question gives the length of the original log as 50 cm (unless there is a typo).

If the two pieces are equal, then each piece would measure 50/2 cm = 25 cm.
