the dimension of bricks =25cm*16cm*10cm ...
the volume of brick 25*16*10=4000cm^3
the dimension of wall=24m,6m,0.4m
the volume of wall 24*6*0.4=57.6m^3
57600000cm^3
so,the no. of bricks built the wall 57600000/4000=14400
the volume of brick 25*16*10=4000cm^3
the dimension of wall=24m,6m,0.4m
the volume of wall 24*6*0.4=57.6m^3
57600000cm^3
