I looked at Mass, Density or Specific Gravity of Bulk Materials, a site in the UK and found that the density of dry sand is 1602 Kg/m^{3 }. There are 1000 grams in a kilogram, 100 centimetres in a metre and one cubic centimetre is a millilitre so the density of dry sand is
Since each bag weight 30 grams, dividing 183 by 60 means each person will need 6 bags of sand. I hope this helps, PS: Email us a photo of the ceremony if you feel inclined. We'd love to add it to this page. Best wishes!
