Given,
Area of path = 6500 m2.
Rate of gravelling = ₹ 5.60 per m3.
Depth = 14 cm = 0.14 m.
Calculating the volume of the gravel,
Volume = Area × Depth
= 6500 × 0.14
= 910 m3.
Calculating total cost of the gravel,
Total cost = Volume × Rate
= 910 × 5.60
= ₹ 5,096.
Hence, cost of covering the path with gravel = ₹ 5,096.
