Given
Dimensions of brick =25cmx15cmx8cm
The volume of brick =25x15x8
=3000cm³
The dimensions of wall =32mx3mx40cm
Let change the m in cm we have
Volume of wall =3200x300x40
=38400000cm³
Bricks required =volume of wall/ volume of one brick
=38400000/3000
=12800 bricks
This is ur ans hope it will help you

length of the wall=32m=3200cm, length of one brick=25cm.
therefore. Length -wise ,the no. of bricks required = 3200÷25 = 128
Similarly, height-wise, no. of bricks required=300÷15=20
Thickness-wise, no. of bricks required=40÷8=5
therefore . The bricks can be arranged in 128 layers , each containing 20 rows of bricks with 5 bricks in each row.
therefore. The no. of bricks required=120×20×5=12800.
