Answer
Given height of wall needed =2.88m
Width of wall needed =50cm =0.5m
Given length of 1 brick =12cm
Breadth of 1 brick =10cm
Area of 1 brick =12×10=120cm2
Area of wall needed =2.88×0.5
Area =14.40m2
Now number of bricks needed =AreaofbrickAreaofwall
No. of bricks needed =12014.40×104=1201440×100
[number of bricks needed =1200].

Verified answer
length of wall=2.88m=288cm
breath of wall=50cm
find the area of wall=l×b
=288×50
=14400cm²
find the area of bricks needed to build
length of bricks =12cm
breath of bricks =10cm
area of brick =l×b
=12×10
=120cm²
no of brick needed =120cm²×14400cm²
... =1728000cm²
