Hope my answer helps you mate :-)

Step-by-step explanation:

Given:

Given:Dimension of brick = l=22.5 cm, b=10 cm, h=7.5 cm

=7.5 cm 

=7.5 cm 

Total surface area of a container= 9.375 m²

Total surface area of a brick = 2(lb + bh + lh) = 2(22.5×10 + 10×7.5 + 22.5×7.5) = 2(225 + 75 + 168.75)= 2×468.75 = 937.5 cm²= 937.5/100×100 m²

Number of bricks that painted out of this container

= total area painted by containers paint / total surface area of a brick

 =9.375(937.5/100×100) =( 9.375×100×100) / 937.5= 937500/ 9375= 100

Hence,100 bricks can be painted out.
