The paint in a certain container is sufficient to paint on area equal to `9. 375m^2dot` How many bricks of dimension `22. 5 c mx10 c mx7. 5 c m` can be painted out of this container?

Explanation

Volume of paint = `9.375 m^2`
= `93750 cm^2`
Dimension of brick = `'22.5 cm×10 cm×7.5' cm`
Total surface area of a brick = '`2(lb + bh + lh)
cm^2`
=`'2(22.5×10 + 10×7.5 + 22.5×7.5)'cm^2`
=` '2(225 + 75 + 168.75)'cm^2`
= `'2×468.75'cm^2`
=`'937.5'cm^2`
Number of bricks can be painted
=`'93750/937.5'
='100'`
