For clarity, a is the unknown. I know x, b and c

I took a look at that quartic formula and experienced that swooooshing sound you hear when something flies right over the top of your head. I'll take another look later in the week (after the festivities) but I don't hold out much hope.
This is supposed to be a simple exercise in discovering the height of liquid in a half-empty cone frustum. I really don't think my lecturer intended it to be so difficult - which leads me to think there is a simpler solution just waiting to reveal itself.
