Answer:
Perimeter of a square shaped floor is = 80m
→ 4a=80
→ a=20m
Thus,
Length (a) = 20 m
Breadth (a) = 20 m
Height (h)= 9.5 m
COST :
Area of four walls and top
2(l+b)h+a² or 2(a+a)h+a²
→ 2(20+20)9.5+20²
→ 2(40)9.5+400
→ 80 x 9.5 +400
→ 760+400
→ 1160m²
Cost of painting 1 m² = Rs. 14
Therefore,
Cost of painting 1160m² = Rs. {1160×14} = Rs. 16240
VOLUME :
Volume of room = l x b x h or a x a x h
= 20 x 20 x 9.5
= 380m³
Hence,
Cost of Painting = Rs. 16240
Volume of room = 380m³
