Answer:

Rs 3502

Step-by-step explanation:

Dimensions = 10 x 9 x 8 m

White washing = LSA + Ceiling

LSA = 2h(l+b)

LSA = 2(10)(9+8)

LSA = 20 x 17

LSA = 340 m²

Area of seiling = lb

= 9 x 8

= 72 m²

White washing = 340 + 72 = 412 m²

Cost per m² = Rs 8.50

Cost for 412 m² = 412 x 8.50

= Rs 3502
