Number of bolts in all boxes = 23681 × 30 = 710430


                                   (We multiply 23681 by 3 and put a zero after it.)


               Example 11:  Each  packet  has  30  combs.  How  many  combs  will  3000
                                   such packets have?


               Solution:           Number of combs in each packet = 30


                                   Number of packets = 3000


                                   Number of combs in all packets = 30 × 3000 = 90000


                                   (We multiply 3 by 3 and put four zeros after it.)
