Answer:

6080

Step-by-step explanation:

First convert all the dimensions in centimetres

Length of wall = 1200 cm

Width of wall = 25 cm

Height of wall = 500 cm

Volume of wall = L × B × H

= 1200 × 25 × 500

= 600000 × 25

= 15000000 cm^3

Now,

Total volume of bricks = 95 % of 15000000

= 95 × 15000000 / 100

= 14250000

Now,

Volume of one brick = 25 × 12.5 × 7.5

= 2343.75 cm^3

No. of bricks = 14250000 / 2343.75

= 6080
