A formica factory produces square plates with sides measuring $y$ centimetres. These plates are sold in boxes with $N$ units and, on the box, the maximum area $S$ that can be covered by the $N$ plates is specified. Due to market demand for larger plates, the factory tripled the measurement of the sides of its plates and managed to gather them in a new box, in such a way that the covered area $S$ was not altered. The quantity $X$, of plates of the new model, in each new box will be equal to: (A) $\frac{N}{9}$ (B) $\frac{N}{6}$ (C) $\frac{N}{3}$ (D) $3N$ (E) $9N$
