A cube with 20-cm-long sides is sitting on the bottom of an aquarium in which the water is one meter deep. Find the hydrostatic force on (a) The top of the cube and (b) One of the sides of the cube.(a) Use the formula of Exercise 16 to show that F = (pgx) A where is the -coordinate of the centroid of the plate and A is its area.
