At first we need to find the surface area of each blog

2lb + 2bh + 2hl = 2*10*5 + 2*5*3 + 2*3*10 = 100 + 30 + 60 = 190 m²

Cost of per m² = ₹ 12.5
Cost of 190 m² = ₹ 12.5 * 190 = ₹ 2375
0
there are 10. blogs
Sry for the mistake....
Plz correct the answer as 23750 as stated by Gautam18

TSA = 190m^2
TSA of 10 blogs = 1900m^2
Cost = 1900 X 12.5
Total cost = 23750rs
