Question

The area of a playground is 4800m² . Find the cost of covering it with gravel 1 cm deep if the gravel cost ₹260 per cubic meter .

Answer 1

Area of playground = 4800 m2
depth of gravel=1cm=1/100 m

Thus volume of gravel=area×depth=4800×1/100=48m^3

Now cost of 1m3 gravel = Rs 260

Hence cost of covering playground = Rs 260 × 48 = Rs 12480
