volume of wall
= l×b×h
= 12×0.6×0.5
= 3.6 m³
1/10th volume is mortar
therefore volume of mortar
= 3.6×0.1
= 0.36 m³
volume of bricks
= 3.6 - 0.36
= 3.24 m³
= 3240000 cm³
volume of 1 brick
= l×b×h
= 18×12×10
= 2160 cm³
no. of bricks
= 3240000÷2160
= 1500 bricks
= l×b×h
= 12×0.6×0.5
= 3.6 m³
1/10th volume is mortar
