Answer:

Step-by-step explanation:

Dimensions of the cuboid,

= 10m x 20m x 25m

Where l= 10m

b = 20m

h = 25 m

LSA of cuboid = 2 h ( l+b )

= 2 ×25 ( 10 +20) = 50(30) = 1500m²

Cost of 1 cm² = ₹ 5

1m² = 10000cm²

Therefore 1500m² =1500 ×10000 = 15000000cm²

Total Cost = 15000000 × 5 = ₹ 75000000
