in order to find the no. of bricks required , we need to divide the volume of the wall by the volume of bricks...
volume of cuboidal wall= l ×b×h
l=10m
b=0.24m
h=4m
10×0.24×4=9.6m^4
volume of a brick=l×b×h
l=0.24m
b=0.12m
h=0.08m
0.24 ×0.12 ×0.08=0.002304m^3
no. of bricks= 9.6/0.002304=9600000/2304=4166.67
hope it is helpful..
THANKS YAAR
