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
