A certain type of milkfish needs 1.5 cubic feet of water to survive. If the milkfish are put in a cylindrical tank whose diameter is 10 feet and whose height is 3 feet. Find the maximum number of fish that can safely be put in the tank. If necessary, truncate your answer.
$\displaystyle {V}=\pi{r}^{{2}}{h}$ where V is the volume, r is the radius, and h is the height for a cylindrical tank.

Number of fish = .
