"The chemical is dispensed to completely fill 25 identical cylindrical containers"
So obviously the volume of each is 1/25 of the whole volume, right? So you know V for one of these cylinders.
"each with a radius of 5 in"
V = pi*r^2*h
You know V. You know r. Plug them in. Solve for h. Should take one line.
235,500 /25 = 9420 is the volume of 1 cylinder.
h =V/πr2
h ≈119.94
