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.
