Answer 2

Answer:

Step-by-step explanation:

Dimention of Wall;

l=8m=800cm

h=6m=600cm

b=22.5cm

olume 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
