1.	The internal measures of a cuboidal room,are 12 m × 8 m × 4 m. Find the total cost ofwhitewashing all four walls of a room, if the cost of white washing is 8 per m^2. Whatwill be the cost of white washing if the ceiling of the room is also whitewashed?
Answer» 2(l+b)h = LSA2(12+8)4 =2(20)4 = 404 = 160m²cost of whitewashing 4 walls =1608 = Rs 1280area of 5 walls = LSA+ lengthbreadth = 160 + (128) = 160 + 96 = 256m²cost of whitewashing with ceiling = Rs 1280 +(96*8)1280+7682048rupee Thanks sir
