Length of Brick = 25cm
Breadth of Brick = 15 cm
Height of Brick = 8 cm
Volume of cuboidal Brick = lxbxh
= 25cm x 15cm x 8cm
= 3000 cm³
Length of wall = 32 m = 3200 cm
Breath of wall = 3 m = 300 cm
Height of wall =40cm
Volume of wall = lxbxh
= 3200cmx300 cm x 40cm
= 3840000 cm³
No.of Brick = volume of wall / volume of 1 brick
=3840000 cm³/3000 cm³
= 1280 Bricks Answer.

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.
