A square has 2 dimensions.  Length and breadth.

Formulae for  cube :
       length of a side = a         number of sides/edges = 12
       number of vertices or corners = 8
        number of diagonals  on the surface = 12 , their length = a √2
           number of diagonals inside cube = 4, their length = a √3
      total number of faces = 6    
      Total surface area = 6 * a² 
       total volume = a³
=================================
Formulae for square 
         length of a side = a            area = a²    perimeter = 4 a
                number of diagonals = 2 
              length of diagonal = a √2
