An aquarium 5 ft long, 2 ft wide, and 3 ft deep is full of water. The weight density of water is $62.5\, lb/ft^3.$

(a) Find the hydrostatic pressure $(\text{in } lb/ft^2)$ at the bottom of the aquarium.

Hydrostatic pressure = $lb/ft^2$

(b) Find the hydrostatic force (in lb) at the bottom of the aquarium.

Hydrostatic force = lb

(c) Find the hydrostatic force (in lb) on one end of the aquarium.

Hydrostatic force = lb
