A chemical reaction involves X, Y, and Z. If you double the concentration of X, the reaction rate is quadrupled. If you triple the concentration of Y, the reaction rate is unchanged. If you multiply the concentration of Z by 5, the reaction rate is multiplied by 625. Find the total order of the reaction.
