Answer:   ₹ 1280     Step-by-step explanation:   Area to be whitewashed = LSA + Ceiling    = 2h(l + b) + lb     = 2  times 4(12 + 8) + (12  times 8)     = (8  times 20) + 96     = 160 + 96 = 256 {m}^{2}    Cost = Area to be washed × Rate  = 256 × 5 = ₹ 1280  Thus, the cost of whitewashing will be ₹ 1280.
