Thus the base width is 16 feet. The volume is the area of the triangular crosssection times the length of the berm. Since you want the volume in cubic yards I would first convert the measurements to yards. The triangular crosssection has base of width 16/3 yards and height 8/3 yards and hence its area is
Hence the volume is (64/9) × (95/3) = 225.2 cubic yards. Harley
