Maximum perimeter of cells with special value in dispersal configuration

Hello The following script calculate perimeter of maximum dispersal configuration of value 1 in matrix x.

"minconfig" is perimeter that is calculated by adding sides of cells(elements) with value 1 when these cells are adjacent to cells(elements) with value 0 or are located in boundary.

for example when matrix x is 3D matrix (size x:(m=4,n=5,k=2))and number of cells with value 1 in dimension 1 is 11 and in dimension 2 is 10, I get 2 results as perimeter by running this script. How can get sum of these results.

Thank you
