Answer 1

Answer:

"Question 4 The paint in a certain container is sufficient to paint an area equal to 9.375 m^2 . How many bricks of dimensions 22.5 cm × 10 cm × 7.5 cm can be painted out of this container? ik this is not the question but use this formula its better to understand and then answer hope this helps. have a nice day

Step-by-step explanation:

Surface area:

Surface area of a solid object is a measure of the total area that the surface of the object occupies and it is always measured in square unit.

 

Hence surface area is also known as total surface area TSA.

========================================================

Given:

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

 

Total surface area of a container= 9.375 m²

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

= 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= total area painted by containers paint / total surface area of a brick

 

=9.375/ (937.5/100×100)

=( 9.375×100×100) / 937.5

= 937500/ 9375= 100

Hence,100 bricks can be painted out.
