Answer 1

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

Answer 2

Answer:

Hope this helps you

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

therefore number of bricks=volume of wall/volume of 1 brick =1687.5 ÷ 10800000=6400 bricks

Therefore number of bricks are 6400.
