Math Help - i need to figure out the price of potting soil by size of container?

the problem i need help solving is the following if anyone would be nice to reply i appreciate it in advance.

i bought 18 yards of potting soil for $300.00 USD, it's a very large pile.
i would like to know how much the soil costs after i fill up the planters or pots as they are called, they come in various sizes such as (1 gallon, 3 gallons, 7, 15, and 25 gallons ) which are the sizes that i use for plants.


18 yds of soil= $300.00
1 gal size pot =$
3 gal size pot =$
7 gal size pot =$
15 gal size pot =$
25 gal size pot =$

is there a formula i can use to easily find out the price of soil in any size container?

Hi sr-,

I first looked up how many gallons in 1 cubic yard.

1 cu. yd. = 201.974026 gal.

That would mean that 18 cu. yd. would be 18(201.974026 gal) = 3635.532468 gal.

The total cost was $300.

Divide $300 by the number of gallons to get $.0825 per gallon.

Now, just multiply the other values times this amount to find your other container costs.

Here is how you figure it, assuming that a yard of soil is actually a cubic yard (cubic foot to gallon conversion from Google calculator).

First you need to convert cubic yards to gallons:

1 cubic foot = 7.48051948 gallons
18 cubic yards = (486 cubic feet)(7.48 gallons per cubic foot) = 3635.53 gallons

Then you set up the formula to determine the cost in dollars, C(g), for a container of size 'g' gallons.

so:

Hope that helps!
