Question

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

Answer 1

Court yard is in the shape of rectangle

Therefore area of the rectangle =lb

lb=3750m2(given)

Here we need to find the cost of gravel

Volume of cuboid=lbh

=3750(0.01)

=37.5m3

Cost for 1m3=6.40

Cost per 37.5m3=37.5(6.40)

=240

Therefore cost =rupees 240
