A symmetrical trapezoid plate has the following dimensions?
The widths of the parallel sides are respectively 2.50 ft and 4.50 ft. The perpendicular distance between those sides is 1.50 ft. The plate is submerged in a liquid is a vertical position with the parallel sides horizontal and the shorter parallel side at the top and exactly in the surface of the liquid. The static moment of the plate with respect to the surface of the liquid will be?
A. 5.43 cu ftB. 4.31 cu ftC. 6.93 cu ftD. 7.68 cu ft
