Question

The area of a rectangular park is 4800m cube find the cost of covering it with gravel 1cm deep if the gravel costs RS 260per cubic metre?

Answer 1

You have made a mistake; the correct one is "The Area of rectangular park is 4800 sq. m...."

Solution:
To find the cost, we need to find the volume of the gravel in cubic metre.
Therefore, vol. of gravel = 4800 x 0.01 .....(since 1cm = 0.01m)
= 48 cubic metre.

Therefore, the cost of gravel = 48 x 260 = ₹12,480/-
