Well, the variable or parameter rcoord must be a list of three numbers
as in the following examples:
rcoord = {0, 0, 0};
Show[Graphics3D[Cuboid[rcoord]]];
rcoord := Table[Random[], {3}];
Show[Graphics3D[Table[Cuboid[rcoord], {20}]]];
rcoord = {{0, 0, 0}, {0, 0, 1}, {0, 1, 1}, {1, 1, 1}};
Show[Graphics3D[Cuboid /@ rcoord]];
