The dimensions of a brick are 16 cm × 12 cm × 4 cm. How many bricks will be required to build a wall 24 m long. 8 m high and 12 m thick, if 10% of the wall is filled with mortar? Correct Answer 27,00,000

Since 10% of the wall is filled with mortar so 90% of the wall is filled with brick.

Number of bricks = (0.9 × volume of the wall) / volume of the brick

⇒ (0.9 × 24 × 12 × 8) / (0.16 × 0.12 × 0.04) = 27,00,000
