Question

The paint in a certain container is sufficient to paint an area of 9.375 square how many bricks measuring 22.5 cm into 10 cm into 7.5 CM can be painted out of the paint in a container​

Answer 1

Answer:

Given,

Area to be painted = 9.375 m2 = 9.375 x (100)2 = 93750 cm2

Dimension of brick = 22.5 cm×10 cm×7.5 cm

Number of bricks that can be painted out of the container = (Area painted by the container)/(Surface area of brick)

Total surface area of a brick = 2(lb + bh + lh) cm2

= 2(22.5×10 + 10×7.5 + 22.5×7.5) cm2

= 2(225 + 75 + 168.75) cm2

= 2×468.75 cm2

= 937.5 cm2

Therefore,

Number of bricks that can be painted = 93750/937.5 = 100

Hence, 100 bricks can be painted out of this container.
