flat surfaces for stability, round surfaces for safety.
triangular ones have at least a sharp edge
other polygons are harder to grip (when force is applied normally to a contact surface the projection of force to some other contact surfaces are not zero or directly normal)

It is just easy to make them that way, and store them that way, not to mention, quite strong that way. It takes time, to make odd shapes and time is money.
