Question

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 25 cm × 11.25 cm × 6 cm?​

Answer 1

Answer:

Dimention of Wall;

l=8m=800cm

h=6m=600cm

b=22.5cm

volume of the wall =lbh=800×600×22.5

=10800000cm³

Dimention of brick;

l=25cm

b=11.25cm

h=6cm

volume of brick =lbh

=25×11.25×6

=1687.5cm³

therefore number of bricks=volume of wall/volume of 1 brick

=10800000

------------------

1687.5

= 6400 bricks

Hence, 6400 bricks will be required to build a wall.
