IKMC 2027 - Grades 5-6 - Self-study SET 6 - Thematic Batch 3 Question 3

A rabbit hutch has 22 cells arranged as shown. Each cell contains a rabbit or shares an edge with a cell containing a rabbit. What is the smallest possible number of rabbits?



Editorial interpretation: The source’s awkward edge wording means every cell contains a rabbit or shares an edge with a rabbit’s cell, as in the source solution.
