 Answered by Mohini Sharma on Tue May 13, 2008 6:40 PM Hey Vijay Kumar Verma, The quantity of cement and sand according to various ratios is given below. 1. 12 mm cement plaster 1:6 = Cement 0.074 Bag per sq .meter Sand 0.018 CUM per Sq. Meter 2. 12MM cement plaster 1:4 = Cement 0.11 Bag. Per Sq. Meter Sand 0.017 CUM per Sq. Meter3. 12 MM cement plaster 1:3 = Cement 0.15 Bag. Per Sq. MeterSand 0.165 cum per Sq. MeterHowever if you want to calculate the quantity of material, the basic formula is given below for the area 10 X 12 feet and thickness 3/8 inch( 10 MM). The quantity of material comes out = 10 X 12 X3/8 X1/12 = 3.75 CFT. This is the volume of wet mortar. Quantity of Dry mortar is 1.2 times of the wet mortar. So cement sand quantity = 3.75 X1.2 =4.5 CFT.     Now ratio given is 1.3 quantity of the cement comes out =4.5 X1/4=1.125 CFT or one bag. Quantity of sand = 4.5x3/4=3.4 CFT. Thanks
