How many bricks will be required for a wall which is 8 m long, 6 m high and 22.5 cm thick if each brick measures 25cm×11.25cm×6cm ?

Easy

Answer

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.
