Question
A large cube (one side measuring 1.0 m) is submerged in water, with the top face of the cube
8.7 m below the surface. Find
a) the force exerted by the water on each face of the cube.
b) the buoyant force on the cube.

top: force=area*weightwater=1*g*densitywater*1^3=1043E6*9.8 Pascals
bottom: force=above+1mwater, twice above.
net force on cube then is bottom-top, directed upward.
Sides: same force at top, times 1.5 to account for average depth being 1.5 meters.
