"An aquarium with length x, width x10, and height x5 holds about 750 cubic feet of water. Find all real solutions of the equation (I wrote it) 750 = x(x10)(x5)."
I got the volume equation correct, right? I've tried dividing the factors of 750 by the factors of 1 (with this one theorem thingy), but I can't seem to get any real solutions. Does anyone know how to do this?
