Sep 01, 2020· So the density of sand will be - weight / Volume = 44.55 / 0.027 = 1650 kg/cum. Now you have the density of sand (mostly its called as dry loose bulk density) Now understand the relation 1 cum = 35.32 cft so if you want to convert it to cft then you need to divide it with 35.32 So you get sand density = 1650 / 35.32 = 46.71 Kg/cft
