If it is filled to half of its volume, what is the height of the water?
This was a question given to me as a practice SAT. (It may not be exactly as written, but this is the best I can remmeber the question.) I've taken other SAT practices and this seems to be the hardest one. Could someone please go over this question and show me how to go about solving it?
