A bag of grass with soil sells for $12.50 and it can cover (10)^6 square inches of ground. what is the price of covering 2 acres land?

Answer 1

6,272,640 square inches = 1 acre
10^6 square inches = 10^6/6,272,640 = 0.16 acre

0.16 acre = $12.50
2 acre = (2 x 12.50)/0.16 = $156.25

The cost covering 2 acres of land is $156.75
