Question

the area of playground is 4800m square .find the cost of covering it with gravel 1 cm deep,if the gravel costs Rs.4.80 per cubic meter

Answer 1

sollution:
1 cm = 0.01m
total cubic meter to fill with gravel = 0.01*4800
                                                         = 48
therefore total cost = 48*4.80
                                 =230.4

Answer 2

We know that 1cm = 0.01m.

The volume is given by 4800 * 0.01

                                      = 48 cubic meters.


Costing = 48 * 4.80

              = 230.4


Hope this helps!
