A lane 150m long and 9m wide is to be paved with bricks each measuring 22.5 cm by 7.5 cm . Find the number of bricks.

Answer 1

Hi friend,
Length of the floor=150m=150000cm
Breadth of the floor=9m=900cm
Area of the floor=L*B
=150000*900
=135000000
Length of the brick=22.5cm
Breadth of the brick=7.5
Area of the brick= L*B
=22.5*7.5
=168.75
No of bricks required=
168.75÷135000000
=8000
Hope it helped you...................
