Question

how many bricks of size 25cm×15cm×6cm are required to make a wall 5m long 2m high and 50cm thick if 10%place is occupied by cement?

Answer 1

Heyyyy mate....


here is your answer...

given dimension of each bricks= 25cm×15cm×6cm

and also dimension of walls = 5m×2m×50cm

so convert it into cm

500cm×200cm×50cm

according to question

given that ,

10 % of walls area occupied by cement

so 500×200×50×10/100= 500,000

now required walls for bricks

500×200×50= 5000,000-500,000=450,0000

now required bricks= dimension of walls / dimension of each bricks

450,0000/25×15×6= 2000 bricks

hope it help you
