volume of brick=25×16×7.5
=3000cm cube
volume of the wall=500×3×80
=120000cm cube
no of bricks needed to build a wall=120000/3000=40
therefore,40 bricks are needed to build a wall
=3000cm cube
volume of the wall=500×3×80
=120000cm cube

vol of bricks=25×16×7.5 cm ³
vol of wall=500×3×80 cm³
so, number of bricks are needed= 500×3×80/25×16×7.5
=120000/3000
=40
