How to draw a sliced cube shape?

I am trying to draw a box, sliced into rectangles. I followed the code from here Need help creating a 3D cube from a 2D set of nodes in TikZ but latex is too difficult so i dont know how to edit the code from there

documentclass[parskip]scrartcl
usepackage[margin=15mm]geometry
usepackagetikz

begindocument
begintikzpicture
foreach x in0,...,4
draw (0,x ,4) -- (4,x ,4);
draw (x ,0,4) -- (x ,4,4);
draw (4,x ,4) -- (4,x ,0);
draw (x ,4,4) -- (x ,4,0);
draw (4,0,x ) -- (4,4,x );
draw (0,4,x ) -- (4,4,x );

endtikzpicture

enddocument


Below is what Id like (edited from paint)

This is a version which is very close to your MWE. There are arguably more elegant ways of doing this with the 3d library and/or tikz-3dplot.

documentclass[parskip]scrartcl
usepackage[margin=15mm]geometry
usepackagetikz

begindocument
begintikzpicture
foreach x in0,...,4
draw (0,x ,4) -- (4,x ,4);
ifnumx=0
draw (x ,0,4) -- (x ,4,4);
else
draw (x ,0,4) -- (x ,0.1,4) (x ,0.9,4) -- (x ,1.1,4)
(x ,1.9,4) -- (x ,2.1,4) (x ,2.9,4) -- (x ,3.1,4)
(x ,3.9,4) -- (x ,4,4);
fi
draw (4,x ,4) -- (4,x ,0);
ifnumx=0
draw (x ,4,4) -- (x ,4,0);
else
draw (x,4,0) -- (x,4,0.1) (x,4,0.9) -- (x,4,1.1)
(x,4,1.9) -- (x,4,2.1) (x,4,2.9) -- (x,4,3.1)
(x,4,3.9) -- (x,4,4);
fi
draw (4,0,x ) -- (4,4,x );
draw (0,4,x ) -- (4,4,x );

endtikzpicture
enddocument
