Following up on what robby_dobby explained - you could re-write your print loop more perlishly, and allow variable dimensions : 
sub printSand{
    for my $inner_arrayref (@_){
       for my $inner_element (@$inner_arrayref){
            print $inner_element;
       }
       print "\n";
    }
}

Of course, it would be more efficient to join the inner element, and print them together, replacing the inner loop with: 
  print join("",@$inner_arrayref),"\n";

and get rid of the separate print newline.
