How many bricks each measuring 25 cm 12.5 cm 16 cm will be needed to construct a wall 8 m long. 5 m high and 22.5 cm thick?
Answer & explanation
Correct answer: option 1
We know that,
Volume of wall = (Length × Breadth × Height)
also,
Volume of wall = x × Volume of one brick
Bricks measurement = 25 cm × 12.5 cm × 16 cm
Wall measurement = 8 m × 5 m × 22.5 cm
We have,
Volume of wall = 800 × 500 × 22.5 = 9000000 cm3
Volume of Bricks = 25 × 12.5 × 16 = 5000 cm3
Number of bricks = \(\frac{9000000 }{5000 }\) = 1800
