Ok i've tried this for a while but i can't get the right answer.  Everyone I know is getting the same answer but for some reason it isn't right.

Area of field- 76171.8
The sod comopany suggests that you need to allow for a 7% waste when determining the amount of sod you need.  What would be the minimum amount of sod that you need to order to include this waste factor?

The answer i have is 81503.8 which is not right

O and +karma for help i guess

thanks

I don't see how that isn't right. You just multiply the are by 107 percent.. i.e. a factor of 1.07 and i got the same answer you did.

You need 81,905.16 units of sod.

Allowing for a 7% waste factor (5,733.12) will leave you with 76,171.80.

Im thinking that the more sod you add the greater the 7% is.  So its not 7% of the area of the field.  Somthing like that but i still cant figure it out.

76,171.80 / (1-.07) = 81,905.16

81,905.16 * .07 = 76,171.80

Shouldn't volume be taken in to account in this problem? That 76171.8 is just the area of your field. You aren't going to put down just a thin layer, you need the depth of what the sod should be right? Somethings gotta happen with volume.
