Answer:
6400
Step-by-step explanation:
Dimention of Wall;
l=8m=800cm
h=6m=600cm
b=22.5cm
volume of the wall =lbh=800×600×22.5
=10800000cm
3
Dimention of brick;
l=25cm
b=11.25cm
h=6cm
volume of brick =lbh
=25×11.25×6
=1687.5cm
3
therefore number of bricks=volume of wall/volume of 1 brick
=
1687.5
10800000
=6400 bricks
Therefore number of bricks are 6400.
