From a piece of calico they cut off two times 8m each, after which 70dm remained in the piece. How many meters of calico were in the piece.

1. Find out how many meters of chintz were cut. To do this, multiply the number of times the chintz was cut by the number of meters:
2 * 8 m = 16 m.
2. Find out how many meters of chintz were in the piece. To do this, to the number of meters of calico that remained after it was cut off twice 8 m each (1 dm = 0.1 m, then 70 dm = 70 * 0.1 = 7 m), we add the total length of the cut chintz :
7 m + 16 m = 23 m.
Answer: the piece contained 23 meters of calico.
