3. An empty box in the shape of a cube
is completely submerged under water. The exterior side of the box has length
L = 1.00 m as shown in Figure 1. The mass of the box is M = 60.0 kg. Assume
the density of water is 1.000x10 3 kg/m3. 4. (30 points) A 3.00 cm diameter garden hose
is used to fill a round hot tub 1.0 m in diameter. How long will it take (in
seconds) to fill the tub to a depth of
1.2 m if the water flows from the hose at a speed of 0.40 m/s?
