Bulk density of sand is in the range of 1520 – 1680 kg/cum.
∵ 1 cubic meter =35.3147 cubic feet
∵ 35.32 CFT = 1520 kg
1 CFT of sand = 1520/35.3147 = 43. 041 Kg
∵ 35.32 CFT =1680 kg
1 CFT of sand = 1680/35.3147 = 47.57 kg
I.e., 1 cu ft of sand is equals to 43 to 47.6 kg
Generally sand is available in the different forms like dry sand, wet sand, wet rammed sand, loose sand and water filled sand. Each of the form will be having different weight. If you know the density of the each form then it’s easier to calculate the quantity of sand per cubic feet in kg by above procedure.
Quantity needed for each kind of sand as follows:
