1 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 =

Volume of 1st class brick with motor =0.2 x 0.1 x

1 Newton = o.101971 kg
1 mm2 = 0.01 cm2
1 cm2 = 100 mm2
1 mm2 = 20 N
100 mm2 = 2000N
1 cm2 = 2000N
2000 N = 203.942 kg
So 20 N/ mm2 = 203.942 kg / cm2
