Expert Answer
It is assumed only inner sides of walls are to be painted. Also Ceiling and floor area are excluded.
assumed dimensions are length = 3.2m , breadth =2.8 m, height = 2.4 m
Hence area to be painted = 2×[ 3.2×2.4 + 2.8×2.4] sq.m = 2×2.4×6 = 28.8 m2
area can be painted using one container = 7.2 m2
no. of container = 28.8/7.2 = 4
cost of painting = 4×460 = Rs. 1840
