    32m=3200cm; 3m=300cm

    Number of bricks required =

    Volume of the wall/volume of a brick

    3200*300*40/25*15*8

    38,400,000/3000=12800

    Number of bricks required is 12800

    SOLUTION :-

    => For wall,

    => Converting into same units, we have ,

    => Length of the wall = 32m = 32 × 100 = 3200cm. => Breath of the wall = 3m = 3 × 100 = 300cm.

    => And the height = 40cm.

    => For brick,

    =>Length of the brick = 25cm.

    =>Breath of the brick = 15cm

    =>Height of the brick = 8cm.

    Now, we have to find number of required bricks.

    =>Number of required bricks = Volume of wall / Volume of brick

    => Number of required bricks = 3200 × 300 × 40 / 25 × 15 × 8 .

    =>Number of required bricks = 128 × 20 × 5.

    =>Number of required bricks = 12800.

    Hence, the required number of bricks is 12800.
