Area to be plastered = 10'*10' = 100'
= 100/10.76 = 9.29sqm
(ie; 1 sqm = 10.76 sqft)
Thickness of mortar layer = 10mm = 0.010m
Volume of mortar required = 9.29*0.010 = 0.09cum
Add 15% for allallowance for calculation of surface and
wastages = (15/100)*.09 = 0.013 cum
Therefore, total volume of mortar required = .09+0.013 =
0.103 cum, say 0.10cum
Sand required for 0.10cum of CM 1:5 = 0.10 cum
Cement required for 0.10 cum of CM 1:5 = (1440/5)*0.10
= 288*0.10 = 28.8 kg
(ie; 1 cum of cement weighs 1440 kg)
