Question

Q. A brick wall having length 10m, 5m height, 25cm thickness has opening of 25m × 1.5m. How many bricks 19cm × 9cm × 9cm are required for the wall.
​

Answer 1

Answer:

6092 bricks.

Step-by-step explanation:

Given :

Length of wall = 10 m

Breadth of wall = 5 m

Thickness = 25 cm

Opening area = 25 m × 1.5 m

Area required for bricks =  ( 10 m × 5 m ) - ( 25 m × 1.5 m )

= > 37.5 m² or 375000 cm

Volume of wall = Area × Thickness

= > 375000 × 25 cm³

Volume of brick = 19 × 9 × 9 cm³

No. of bricks required for the wall = volume of wall / volume of one brick.

= > 375000 × 25 cm³ /  19 × 9 × 9 cm³

= > 6091.6

Almost 6092 bricks.
