Question

The area of of a courtyard is 3750m. Find the cost of covering it with gravel to a height of 1 cm if the gravel costs ₹ 6.40 per cubic metre

Answer 1

Height of Gravel = 1 cm. = 0.01 m.

Area of Courtyard = Area of Gravel.

=> Volume of Gravel = Area of Courtyard * Height of Gravel

=>                                = 3750 * 0.01 cubic meter.

Therefore, Volume of Gravel = 37.5 cubic meter.

Hence, cost of Gravel is 37.5 * 6.40 = 240 Rs.
