This problem has been bugging me for a month now... anyhow, for those of you who are familiar with this retaining wall problem, when calculating for F2 = (45)(4)(9)... I'm not understanding why we would include the 4 in this equation, which would be the height of the soil above the water table... and then it's multiplied by the height of soil below the water table??? Previous iterations of these problems that I've seen don't seem to jive with this rationale. Can anyone help to explain this? Thanks!
