Answer:

13pieces

Step-by-step explanation:

Length of the  wire = 42 meter

Length of piece of wire = 3.2 meter

No. of pieces = 42/3.2

                      = 42*10 / 3.2*10

                      = 420/32.0

                      = 420/32

                     = 13.125

No of pieces = 13

0.125m of wire is remaining
