Today’s question is how many bags of soil do you need to fill an area that is 12 cubic feet?

The short answer is it depends on their size. Here is the explanation:

Most bags of soil are sold in 1 cubic feet sizes, but they are sometimes sold in three cubic foot size. To make things even more confusing, some bagged soil is sold by the quart.

A cubic foot of soil is approximately equivalent to approximately 25.75 quarts.

If you are buying soil that is sold by the cubic foot just divide the amount you need by the amount that is in the bag to get the number of bags you need. In this example, the reader needs 12 cubic feet. If she is buying 1 cubic foot bags then she will need 12 bags (12/1 = 12). If she is buying 3 cubic foot bags then she will need 4 bags (12/3 = 4).

If you are buying soil that is sold by the quart then first change cubic feet to quarts by multiplying it by 25.75. Then divide it by the number of quarts in the bag. In this example, the reader needs 12 cubic feet or 309 quarts. If he is buying 8 quart bags then he will need 39 bags (309/8 = 38.6). If he is buying 16 quart bags then he will need 20 bags (309/16 = 19.3). If he is buying 32 quart bags then he will need 10 (309/32 = 9.7).

If you want to purchase soil by the cubic yard (which is cheaper if you have a way to haul it) then divide the amount you need by 27 (there are 27 cubic feet in a cubic yard). In this case you will need 0.44 cubic yards, but since they generally sell by the half yard you will need to round up and purchase half a yard.

      True, but this reader specifically asked for bags – which is what you have to use if you can’t haul or get delivery
