27 1 cu ft bags or 9 3 cu ft bags.
There are 764.554858 liters in a cubic yard of topsoil (or anything else).
bags of what?
A 40 lb bag of topsoil typically covers about 3-4 square feet at a depth of 1 inch. Since 1 cubic yard is equal to 27 cubic feet, you would need approximately 9-12 bags to make up 1 cubic yard of topsoil.
It depends on the size of the bag of mulch. If the bags are 3 cu.ft., 9 bags equal 1 yard, but if the bags are 2 cu.ft., approximately 13-14 bags equal 1 yard.
You already have a square yard of topsoil, so how does 20 inches of depth get you the volume of topsoil? There are 36 inches in a yard, and you have 20 inches of topsoil depth that's 20/36ths of a yard of topsoil depth. That's 0.555... or about 0.56 yards. The volume of topsoil is 1 yard by 1 yard by 0.56 yards, or about 0.56 cubic yards of topsoil.
It depends on the size of the bags. There are 20 hundredweights to the to but as health and safety czars do not allow builders to lift that, most bags are now 1/2 a cwt so that will mean 40 bags to the ton.
40 bags of 90 will give you 1 yard
One ton is equal to 2,000 pounds. Since each bag of topsoil weighs 40 pounds, you would divide 2,000 by 40. This means you would need 50 bags of 40-pound topsoil to equal 1 ton of dirt.
The cost of 1 yard of topsoil can vary depending on location and quality, but it typically ranges from $20 to $50. Delivery fees may also apply.
On average, 1 cubic yard of topsoil weighs about 2,000 to 2,700 pounds (900 to 1,225 kg), depending on its moisture content.
One cubic yard is equivalent to approximately 764 liters. To determine how many 20-liter bags of soil make up 1 yard, you divide 764 liters by 20 liters per bag. This results in about 38.2 bags. Therefore, you would need approximately 39 bags of 20 liters each to make up 1 cubic yard.
A cubic yard of topsoil, if compacted to get the air pockets out will weigh more than 1 tone. If the topsoil is loose, a cubic yard of it could weigh about 1 ton. A lot depends on the topsoil, and whether it has more stone dust or less in it. The more moist the topsoil is, the more likely it will weigh more than a ton.
