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
