To determine the number of bricks used to construct the wall, we need to calculate the volume of the wall and the volume of a single brick.

1. Volume of the wall:
The dimensions of the wall are given as 270 cm x 300 cm x 350 cm. The volume of the wall can be calculated by multiplying the three dimensions together:

Volume of the wall = 270 cm x 300 cm x 350 cm
= 28,350,000 cubic cm

2. Volume of a single brick:
The dimensions of a single brick are given as 22.5 cm x 11.25 cm x 8.75 cm. The volume of a single brick can be calculated by multiplying the three dimensions together:

Volume of a single brick = 22.5 cm x 11.25 cm x 8.75 cm
= 2,431.640625 cubic cm

3. Accounting for mortar:
It is stated that 1/8th of the space is covered by mortar. This means that 7/8th of the space is occupied by bricks. To calculate the effective volume of a single brick considering mortar, we can multiply the volume of a single brick by 7/8:

Effective volume of a single brick = (7/8) x Volume of a single brick
= (7/8) x 2,431.640625 cubic cm
= 2,135.25390625 cubic cm

4. Calculating the number of bricks:
To find the number of bricks used, we can divide the volume of the wall by the effective volume of a single brick:

Number of bricks = Volume of the wall / Effective volume of a single brick
= 28,350,000 cubic cm / 2,135.25390625 cubic cm
≈ 13,250.725

Rounding off to the nearest whole number, the number of bricks used to construct the wall is 13,251.

Therefore, the correct answer is option B) 11200 cm (rounded off to the nearest whole number).
