Quick rates of change question:
A rectangular water tank has a square base with sides of length 0.55m. Water is poured into the tank so that the fluid volume in the tank increases at a constant rate of 0.2m$^3$ per hour. How fast is the water leveraging in metres per hour?
I've worked out the volume of the water tank V=0.55$^3$=0.166375m$^3$. From the question, dv/dt=0.2m$^3$ p/hr but I do not know what to do next. Any help will be beneficial.
