Answer 2

Answer:

Hence, the required number of bricks is 12800.

Step-by-step explanation:

→For wall,

Converting into same units, we have ,

⇒Length of the wall = 32 m = 32 × 100 = 3200 cm.

⇒Breath of the wall = 3m = 3 × 100 = 300 cm.

⇒And the height = 40 cm.

→For brick,

⇒Length of the brick = 25cm.

⇒Breath of the brick = 15 cm

⇒Height of the brick = 8 cm.

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.
