Sfumature Eff Azzuro is a 3" x 13" ceramic tile from Centura's Sfumature range. Wall installation is the rating here, so backsplashes and shower surrounds are in scope and floors are not. It ships 52 pieces to a box, covering 10.76 sq ft, or 0.2069 sq ft a piece. A ceramic body is lighter than porcelain and easier to cut on site, which is why it is the usual choice for walls and backsplashes.
