1m = 100 cm then 100 divided by 8.5 = 11 pieces and 0.765 left over.
2m = 200cm then 200 divided by 8.5 = 23 pieces and 0.529 left over
3m = 300 cm, then 300 divided by 8.5 = 35 pieces and 0.294 left over
4m = 400 cm then 400 divided by 8.5 = 47 pieces and 0.059 left over MINIMUN
5m = 500 cm then 500 divided by 8.5 = 58 pieces and 0.823 left over
With 4 meters he gets 47 pieces and has 0.5 centimeters left
Of course with 17 meters, he gets 200 pieces and nothing left over
