ASSUME PROPORTION IS [ 1: 6 ]
AREA = 27.88 SQ MT
SET VOLUME = 27.88 X .012 = 0.334 CUM
30 % EXTRA FOR JOINT FILLING AND UNIFORM SURFACE =
0.334+0.36 = 0.694 CUM

[ 1 CUM SET MORTAR = 1.25 CUM DRY MORTAR ]

SO , 1.25 X 0.694 = 0.867 CUM
0.867 / 7 = 0.123 CUM CEMENT
NO OF BAGS = 28.88 X 0.123 = 3.57 BAGS = 178.5 KGS
SAND = 0.867 X 6 = 5.2 CUM
