#### Question

The paint in a certain container is sufficient to paint on area equal to 9.375 m2. How manybricks of dimension 22.5 cm × 10 cm × 7.5 cm can be painted out of this container?

#### Solution

We know that

Total surface area of one brick = 2 (lb + bh + hl )

`=2[22.5xx10+10xx7.5+22.5xx7.5]cm^2`

`=2[468.75]cm^2`

`=937.5cm^2`

Let n number of bricks be painted by the container

Area of brick= `937 .50 cm^2`

Area that can be painted in the container

`= 93755m^2= 93750cm^2`

`93750 = 93750cm^2`

`n=100`

Thus, 100 bricks can be painted out by the container.
