Your child and your cousin’s child are second cousins. You and the children of your parents’ second cousins are third cousins and share at least one great-great-grandparent. And so on with the fourth, fifth, and sixth cousins. A relationship that is removed is one that exists in two different genealogical generations.
A piece of surfaced (sanded smooth) 2×4 lumber actually measures 1½ inches thick and 3½ inches wide. In rough-cut condition, a 2×4 is slightly less than 2 inches thick and approximately 4 inches wide. When wood is milled from a rough to a smooth surface, it loses about ¼-inch from each of its four sides.
