Question

paint in a certain container is sufficient to paint an area equal to 9.315 m.
y bricks of dimensions 22.5 cm x 10 cm x 7.5 cm can be painted out of this
container?​

Answer 1

Answer:

22.5×10×7.5=1687.5cm^3

area=1687.5×9.315=15719.0625

Answer 2

Answer:

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

Given :

• Dimension of brick = l=22.5 cm, b=10 cm, c=7.5 cm

• Total surface area of a container = 9.375 m²

To find :

• Bricks can be painted out by the paint of the container =?

Step-by-step explanation:

Dimension of brick = l=22.5 cm, b=10 cm, c=7.5 cm [GIVEN]

 Total surface area of a container= 9.375 m² [Given]

= 9.375 x (100)² cm²

= 9.375 x ( 10000) cm²

= 93750 cm ²

Total surface area of cuboid = Total Surface area of a brick = 2(lb + bh + lh) 

Substituting the values in the above formula, we get,

= 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 = Area that can be painted out by the paint of the container/Surface Area of Brick.

Substituting the values, we get,

 

=9.375/ (937.5/100×100)

=( 9.375×100×100) / 937.5

= 937500/ 9375

= 100

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