🔄How many bags make a cubic yard?

13.5 exactly, because 27 ÷ 2 = 13.5. In practice you buy 14, since nobody sells half a bag. Two cubic yards is 27 bags, three yards is 41, and five yards is 68 — at which point you are carrying 3,500 lb of mulch, and one delivery starts to look sensible.

Eighteen of the 1.5 cu ft bags that topsoil and raised bed mix usually come in, or 27 of the 1 cu ft size used for compost and garden soil. Soil is also sold by weight, and those bags have to be converted through density rather than counted: 40 lb of a peat-based potting mix is about three times the volume of 40 lb of screened mineral topsoil.

Multiply the number of bags by the size printed on them. Ten 2 cu ft bags is 20 cubic feet; ten 3 cu ft bags is 30. The only trap is bags sold by weight — a 50 lb bag of sand is about 0.5 cu ft, but a 50 lb bag of a lighter material holds far more volume, so weight bags have to be converted through density.

Because the limit is what one person can lift. Shredded hardwood at about 52 lb for 2 cu ft is near the practical ceiling, so denser materials come in smaller bags — 1.5 cu ft for topsoil, 0.5 for stone and sand — while light pine bark and cypress are packed at 3 cu ft and still weigh less.

Yes. When a supply yard says ‘a yard of mulch’ they mean a cubic yard: 27 cubic feet, roughly a cube you could stand in the middle of and touch the sides. It is not a linear yard, and it is not a truck load — a load is whatever the truck happens to be carrying, usually 5 to 10 yards.

Fewer than the maths suggests, because bags do not stack without gaps. Fourteen 2 cu ft bags contain a cubic yard of material but occupy closer to 1.2 cubic yards of space once they are piled in a car boot, which is why a load that should fit rarely does on the first attempt.
