Area of courtyard = 3750 m^2
Height after graveling = 1 cm = 0.01 m
Volume of gravel = Area × Height
= 3750 × 0.01
= 37.5 m^3
Cost of graveling = Volume × Rate
= Rs 37.5 × 6.40
= Rs 240
Height after graveling = 1 cm = 0.01 m
Volume of gravel = Area × Height
= 3750 × 0.01
= 37.5 m^3
Cost of graveling = Volume × Rate
= Rs 37.5 × 6.40
= Rs 240
