Answer :
Answer:
Number of bricks require to make the walls[tex]=2880bricks[/tex]
Step-by-step explanation:
The number of bricks needed to make the wall:
= Volume of the wall/volume of one brick
The wall and the brick are in the shape of a cuboid:
Volume of the Cuboid= [tex]Length*Width*Height[/tex]
For wall:
[tex]Length= 8 m\\Width=22.5 cm= 0.225 m \\Height=4 m \\[/tex]
Volume of the wall=
[tex]=8*0.225*4\\\\=32*0.225\\\\=7.2m^3[/tex]
For one Brick:
[tex]Length=25 cm=0.25m\\Width=12.5 cm=0.125\\Height= 8 cm=0.08m[/tex]
Volume of one brick= [tex]Length*width*Height[/tex]
[tex]=0.25*0.125*0.08\\\\=0.0025m^3[/tex]
Number of bricks required to make the wall:
[tex]=7.2/0.0025=2880 bricks[/tex]
[tex]=2880bricks[/tex]
