Answer 1

Please mark my answer as brainliest.

Answer 2

dimensions of wall -

6m= 600cm

600cm

3m= 300cm

volume of wall= l×b×h

= 600× 600×300

= 108,000,000 cm^3

dimension of brick -

30cm

15cm

7.5cm

volume of a brick= l×b×h

= 30×15×7.5

= 3375 cm^3

numbers of bricks required to make a wall =

108,000,000/3375

= 32000 bricks.
