Solutions:
we are given in the problem
Pat has the 3 rows of shells.
There are 4 shells in each row.
Here we are given with 4 shells in each row and the number of rows is 3 , so we will multiply these two get the total number of shells.
Hence we get
Total number of shells[tex] 3*4=12\\ [/tex]
It mean that Pat have a total of 12 shells.
