Answer 2

Answer:

100 bricks

Step-by-step explanation:

Dimensions of brick:

Length (l) = 22.5 cm

Width (w) = 10 cm

Height (h)= 7.5 cm

Brick is in the shape of cuboid.

So, Total surface area of Brick = $2(lw+wh+hl)$

Total surface area of Brick = $2(22.5 \times 10+10 \times 7.5+7.5 \times 22.5)$

                                            = $937.5 cm^2$

We are also given that the paint in a container is sufficient to paint an area equal to 9.375 m square .

$1 m^2=10000 cm^2$

So, $9.375  m^2=10000 \times 9.375  cm^2$

$9.375  m^2=93750 cm^2$

Thus the paint in a container is sufficient to paint an area equal to 93750 cm square .

So, number of bricks can painted out of this container= $\frac{\text{Total area}}{\text{Area of 1 brick}}$

                                                                                         = $\frac{93750}{937.5}$

                                                                                         = $100$

Hence 100 bricks can be painted out of given container.
