a wall is 8m long,4m high, and 22.5cm thick. how many bricks of 25cm Length, 12.5cm breadth and 8 CM high are needed to build th

s344n2d4d5 [400]

Answer:

Number of bricks require to make the walls $=2880bricks$

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= $Length*Width*Height$

For wall:

$Length= 8 m\\Width=22.5 cm= 0.225 m \\Height=4 m \\$

Volume of the wall=

$=8*0.225*4\\\\=32*0.225\\\\=7.2m^3$

For one Brick:

$Length=25 cm=0.25m\\Width=12.5 cm=0.125\\Height= 8 cm=0.08m$

Volume of one brick= $Length*width*Height$

$=0.25*0.125*0.08\\\\=0.0025m^3$

Number of bricks required to make the wall:

$=7.2/0.0025=2880 bricks$

$=2880bricks$
