How many 25 cm × 11.25 cm × 6 cm bricks will be required to construct an 8 m × 6 m × 22.5 cm wall?(ignoring other material used)
Answer & explanation
Correct answer: option 2
Number of bricks = \(\frac{ measurement \; of \; wall }{ measurement \; of \; each \; bricks }\)
= \(\frac{800 × 600 × 22.5}{25 × 11.25 × 6}\)
= 6400
