Area =100 m^2.
Thickness = 4cm
= 0.04M
Volume = 100 * 0.04
= 4M^3
The Volume of cement = dry volume/sum of the ratio.
= 1.54/1+2+4
= 0.22 M^3
For 4 m^3 = 0.22*4.
= 0.88M^3.
So ,0.90m^3 is the right answer.
Thickness = 4cm

Area = 100 M2.
Thickness = 4 cm = 0.04m.
Volume = 100*0.04 = 4 M3.
Add 54% of Dry vol = 4+ 54/100 * 4 = 6.16 m3.
Cement = 1/7 *6.16 = 0.88 m3.
Thickness = 4 cm = 0.04m.
Volume = 100*0.04 = 4 M3.
Add 54% of Dry vol = 4+ 54/100 * 4 = 6.16 m3.
Cement = 1/7 *6.16 = 0.88 m3.

Qc = (1.65 * 100* 0.04)*1/7.
Qc = 0.94m^3.
Qc = 0.94m^3.

The volume of concrete= 100 * .04 = 4.
10% increase for the unevenness + 50% increase for dry volume =4*1.1*1.5 = 6.6cum,
Cement=6.6/(1+2+4).
10% increase for the unevenness + 50% increase for dry volume =4*1.1*1.5 = 6.6cum,
Cement=6.6/(1+2+4).

The volume of wet concrete = 100*0.04 = 4.
Increased mortar by 65% in dry mortar.
The volume of dry mortar=4+0.65*4=6.6.
Now,
Cement QTY = 6.6/7 = 0.94ans.
Increased mortar by 65% in dry mortar.

100*0.04=4*1.54=6.16/7=0.88ans.
So, 0.90cum is the right answer.
