Shown is the cross-section of a gravity retaining wall. Knowing that b = 14 ft and h = 28 ft, locate the center of gravity of the dam in the x-y plane. The retaining wall is uniform in cross-section (prismatic), so point G represents the c.g. in the x-y plane and the centroid of the cross-sectional area shown. Enter y below, and express your answer in feet to the nearest 0.1 ft. b/2 h/10 b/4
