3D Shapes in your kitchen

We know that 2D shapes are flat shapes with just one face.  3D shapes are not flat because they have many faces.  Many 3D shapes are prisms because they have rectangular sides.  We've been learning the names of some prisms using boxes that can be found in our kitchen cupboards! 

  

If you go to a supermarket, what 3D shape do you think you'd see the most of?
