Step-by-step explanation:

[tex]no \: of \: bricks = \frac{volume \: of \: wall}{volume \: of \: one \: brick} \\ \\ = \frac{10 \: m \times 4 \: m \times 24 \: cm}{24 \: cm \times 12 \: cm \times 8 \: cm} \\ \\ = \frac{1000 \: cm\times 400 \: cm \times 24 \: cm}{24 \: cm \times 12 \: cm \times 8 \: cm} \\ \\ = \frac{1000 \: cm\times 400 \: cm }{ 12 \: cm \times 8 \: cm} \\ \\ = \frac{400000}{96} \\ \\ = 4166.67 \\ \\ \approx \: 4167[/tex]

Hence, approximately 4167 bricks would be required to built the wall of given dimensions.
