A brick with a polished surface is submerged in non-moving constant-density water. Select ALL of the true statements regarding force due to water pressure on the surface. (a) The force due to water pressure on the polished surface can be calculated by integrating the pressure due to water across the surface's area. (b) Generally, the center of pressure of a submerged surface is above its centroid. (c) The force due to water pressure on the polished surface is a function of how deep the surface's centroid is underwater. (d) The average water pressure on the polished surface is the pressure at the surface's centroid
