lets the take size of brick is .230*.115*.075. now calculate
the quantity for 10 cum.

Area of one brick without mortar -0.00198375 Cum
No of brick in 10 cum= 10/0.00198375 (Area of bricks).
=5041 nos of bricks.

now calc. the bricks quantity in 10 cum with mortar.

lets take the mortar used 10mm in brickwork then
size of brick will be taken with mortar is =.240*.125*.085=
0.00255 (Area of one brick with mortar).

now in 10 cum brickwork no of bricks calculated with mortar
is=10/0.00255 =3922 nos

calculate the mortar in cum= bricks without mortar- bricks
with mortar= 5041-3922=1119 nos
Now area of brick without mortar is .230*.115*.075*1119=2.22cum

now 15% for frog filling and wastage taken in acc.

=2.22+2.22*15/100=2.55 cum

Dry volume is the 1/3rd of wet volume of mortar=
2.55+2.55/1/3=3.40 cum.

now the ratio is 1:6=7

3.40*14%=.486 cum cement
3.40*86%= 2.92 Cum Sand

=.486/.0347= 14.01 bags/10 Cum
= 14.01*6=84.06 Bags/10 Cum
