The third piece is 59 cm long.
Add the first two pieces up. 7+34= 41. Since the whole stick is 100 cm long, subtract 41 from 100 to find the length of the third piece. 100-41=59.
59 cenitmeters ;
The third piece of the stick is 59 centimeters long. To find this, we summed the lengths of the two known pieces and subtracted that total from the original 100-centimeter stick. Therefore, the calculation showed that 100 cm minus 41 cm equals 59 cm.
