how to calculate sand

 Quantity Of Sand

Cement : Sand :: 1:5

Quantity of Sand = Quantity of Cement x 5

∴ Quantity of Sand = 2.333 x 5= 11.665 CFT

1 m³=35.3147 Cubic Feet (CFT)

∴ Quantity of sand = 11.665/35.3147 = 0.330 m³

Density of sand = 1600 kg/m³

∴ Weight of the sand= 0.330 x 1600= 528 kg (0.528 tonnes)
