cubic meter contains 500 bricks
The Standard size of the 1st class
brick is 190mm x 90mm x
90mm and motor joint should be
10mm thick
So brick with motor=200 x 100 x
100.
Volume of 1st class brick = 0.19 x
0.09 X 0.09 = 0.001539
cu.m
Volume of 1st class brick with
motor =0.2 x 0.1 x 0.1=0.002
cu.m
No. on bricks per 1cu.m= 1/
volume of1st class brick with
motor
=1/0.002
= 500 nos of bricks.
So 500 bricks needed(aprox).
