You have a 30 1/4 inch strip after trimming the ends. You need to specify how close the holes can be to the end of the remaining strip. The diameter of the holes is also necessary, to make sure part of the hole does not go beyond an edge
If the holes are very small and can be drilled right to the edges, you need 11 gaps in 30.25 inches. That would be 2.75 inches between holes.
