Answer / sachin

Assume proportion 1:5

total work = 300 sq.ft.
convert in m3 = 27.87 m3
thickness is 12 mm = 27.87 *.012
total volume = .33 m3
proportion is 1:5 = 1+5 = 6
so = .33 / 6
so = .055
cement per bag volume is 1440/50 = .034
so .55 /.034 = 16.17 bag

Answer / faisal farooq

area for plaster=300 sft
thikness=12mm=.039ft
wet volume=300x0.039=11.70cuft
dry volume=11.70x1.54=18.01cuft
ratio (1:5)
sum of ratio=1+5=6
quantity of cement=1/6x18.01=6.06 cuft
bags of cement=6.06/1.25=4.80 say 5 bags

Answer / syed faizan qadri

4.5 bags

Answer / amio

Let's assume
1bag of 50kg cement occupies 0.035cum.
1bag of 50kg cement occupies 0.035cum.
my basis of mortar mix is 1:5
so there are a total of 6bags (1+5)
in 1cum of cement mortar, no of 50kg bags will be
= 1/.035
=28.57 bags of 50kg each
so cement quantity will be (28.57/6)*1=4.76 bags(say 05bags
50kg each)
and sand quantity will be (28.57/6)*5=23.81 bags (say
24bags, 50kg each)

hope this will work
