A couple of reasons.
A submarine isn't shaped like a cube because water flowing around a cube would make noise that could be heard on sonar. Submarine forces work very hard to make their submarines less audible.
It also isn't shaped like a cube because depending on the way the cube is oriented in the water, it would take more power to push the submarine through the water.
A combat submarine isn't shaped like a sphere because a sphere won't hold as much load as they would the shape they are made. They have made spherical-shaped submersibles for extremely deep-water exploration because a sphere is the most pressure-resistant shape.
