  weight of an the object is proportional to volume.

  when you triple height , volume triples

  when you triple sides then the volume which is proportional to area of face

  which in turn is proportional to square of the sides

  so volume is proportional to square of the sides.

  so volume must increase 9 times.

  so total volume is increased 27 times.

  weight = 5.4 lbs
