Answer:
Your answer is here
Step-by-step explanation:
the area of walls = curved surface area of cuboid ( CSA )
here - height (h) = 9 m
length (l) = 12m
breadth (b) = 10m
CSA of cuboid = 2h ( l + b )
= 2 x 9 ( 12 + 10 )
= 18 ( 22 )
= 396m^2
cost of 1m^2 = 8 rupees
cost of 396m^2 = 8 x 396
= 3168 rupees.
Hope it helps you.
