✪ Solution :-
Total volume of the wall = L × B × H
→ 11 × 3.5 × 0.4
→ 15.4m³
Amount of volume occupied by sand and cement = 1/10 × total volume
→ 1/10 × 15.4
→ 1.54 m³
Volume of bricks needed =
→ 15.4 - 1.54 = 13.86 m³
Vol of 1 brick = L × B × H
→ 0.22 × 0.10 × 0.07
→ 0.00154 m³
Number of Bricks = Volume of bricks needed/ volume of single brick
→ 13.86/0.00154
→ 9000
∴ 9000 bricks are needed
