for 1m3 of brick work = 500 nos needed but it is theoritical only, 490 bricks is needed, to check this take total volume of brick work and then count the no how much brick is needed for that volume and then covert it for 1m3 volume you will get doubts clarified

size of bricks with joint = 0.241*0.126*0.088,Number
of bricks =1 /(size of bricks with joint) = 1 /
(.241x0.126x0.088) = 1/ (0.002672208) =374.22 / cum we
take 375 number of bricks / cum

Number of bricks =1 /(size of bricks with joint)(i am
taking half thickness of a joint with a brick size)
= 1 /
(.235x0.120x0.082)
= 1/ (0.0023125)
=432.43 / cum we
take 432 number of bricks / cum

Given Size of brick = 0.229m X 0.114m X 0.076m
Considering the brick wall thickness is 114mm
Size of brick with 12mm mortar = 0.241m X 0.114m X 0.088m
Volume of brick with mortar =0.0024 m3

Volume of brick wall with mortar =1 m3

Volume of brick wall with mortar /
No's of brick in wall = --------------------------------
Volume of brick with mortar

Hi
R u aware of faloowing things
1:Naminal thickness and Actuval tickness of wall?
2;Dry volume of mortor ?
3: Extra mortor rqd forg filling ?
4:westage norms of different meteriels?
5:Standard jont thickness in maasonary wall if yes R u
aware of practical thk ness maintained by masons on site
All thise factores we have to considere then only we ll
able get rqd qty of metereal
