# 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?

Given:

The dimensions of the brick are:

l = 22.5 cm

b = 10 cm

h = 7.5 cm

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

= [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

Area that can be painted by the paint of the container = 9.375 m2
As 1 m2 = 10000 cm2

= 93750 cm2

= 100

Therefore, 100 bricks can be painted out by the paint of the container.
