Absent angular momentum from rotation, absent tidal forces from nearby heavenly bodies, the laws of Newtonian physics require that all heavenly bodies be spherical! Suppose the earth was made entirely of diamond, the strongest, hardest material known. Now suppose the diamond Earth were formed in the shape of a simple cube. Due to the immense gravitational forces caused by simply supporting the weight of the pyramidal corners of the cube, the whole structure would simply collapse! If a cubical Earth planet is unstable then a flat Earth planet would be even less so.
