Answer:

# convert all the units to m.

The volume of brick:- 22 cm = 0.22m, 10cm = 0.1m, 7cm = 0.07m

                                 :- 0.00154 m^3

The volume of the wall:- 33m  * 3.5m * 40cm [0.4 m] = 46.2m^3.

Given that cement and sand occupy 1/10 of the wall, so the bricks will occupy 9/10 of the wall.

9/10 of 46.2m^3 = 41.58 m^3.

No of bricks required :- 41.58 / 0.00154

                                     :- 27, 000.

Answer :- 27,000 bricks
