There are 5 rows - there are 4 items in each row - there are NO more than 10 items

Any idea how this can be solved?

Draw a 5 pointed star connecting all the vertices.

Place one item at each vertex and one item at the intersection of the lines joining the vertices.

Thus, 10 items in 5 rows with 4 items in each row.
