Question : Height of water in rectangular tank = ?

To answer this question we need
2) Base area of rectangular tank

Statement 1: The base of the cylindrical tank has the same area as the base of the rectangular tank.

i.e. Heights of water in both tank should also be same as the volume of the water remains the same hence
SUFFICIENT

Statement 2: The radius of the cylindrical tank is 3 feet

Base area of rectangular tank is still unknown hence
NOT SUFFICIENT
