Question

The area of a courtyard is 3750m2. Find the cost of covering it with gravel to a height of 1cm if the gravel costs Rs 6.40 per cubic metre

Answer 1

Answer:

Step-by-step explanation:area of courtyard=3750m^2

Height of gravel to be covered=0.01m

Volume of gravel=3750×0.01

Cost of graveling 1m^3=₹6.40

So, cost of graveling 37.5m^3=37.5×6.40

=₹240
