The paint in a certain container is sufficient to paint an area equal to 9.375 m². How many bricks of dimensions 22.5 cm × 10 cm × 7.5 cm can be painted out of this container?

Lenght of one brick l = 22.5 cm, breadth b = 10 cm and height h = 7.5 cm
Total surface area of brick = 2(lb + bh + hl) = 2(22.5 × 10 + 10 × 7.5 + 7.5 × 22.5) cm²
= 2(225 + 75 + 168.75) cm² = 937.5 cm² = 0.09375 m²
Number of bricks to be painted
= Total paint available/paint for one brick = 9.375 m²/0.09375 m² = 100
Hence, the paint of this container can paint 100 bricks.
