A cube with 30-cm-long sides is sitting on the bottom of an aquarium in which the water is one meter deep. (Round your answers to the nearest whole number. Use 9.8 m/s2 for the acceleration due to gravity. Recall that the weight density of water is 1000 kg/m3.)

(a) Estimate the hydrostatic force on the top of the cube.

(b) Estimate the hydrostatic force on one of the sides of the cube.
