Hey! I didn't do engineering studies, but looking at your formula sheet and using Hyperphysics, it LOOKS like water pressure can be calculated by the formula P=pgh, where p is the density of the liquid, g is acceleration due to gravity, and h is the height of water above the point. Therefore, P=1*9.8*60=588, which is closest to B, which happens to be the correct answer. I don't know if I've got there in the right way, hopefully someone who did Engineering studies can help out!
