How to Convert Oven Recipes to Air Fryer
Calculating sand is a volume-to-weight conversion. Measure your area, choose a depth, and this calculator handles the rest — including weight by sand type.
The basic rule:
- Volume: Area (sq ft) × Depth (inches) / 12 = cubic feet. Divide by 27 for cubic yards
- Weight varies by type: play sand ~2,500 lbs/yd³, fill sand ~2,700 lbs/yd³, masonry sand ~2,800 lbs/yd³
- A 50-lb bag of sand contains about 0.5 cubic feet. One cubic yard = approximately 54 bags of 50-lb sand
For sandboxes, use clean play sand rated for children — it is washed and screened to remove dust and debris. For paver bases, use coarse masonry sand (concrete sand). Fill sand is the cheapest option for grading and leveling.

Frequently Asked Questions
How much sand do I need for a sandbox?
For a 10' x 10' sandbox at 8 inches deep, you need about 2.5 cubic yards or 3.1 tons of play sand. That is roughly 124 bags of 50-lb play sand. A 6' x 6' sandbox at 6 inches needs about 0.67 cubic yards — around 33 bags.
How much does a cubic yard of sand weigh?
Dry sand weighs 2,500-2,800 lbs per cubic yard depending on the type. Play sand: ~2,500 lbs (1.25 tons). All-purpose: ~2,700 lbs (1.35 tons). Masonry sand: ~2,800 lbs (1.4 tons). Wet sand can weigh 20-30% more.
How many 50-lb bags of sand are in a cubic yard?
Approximately 54 bags of 50-lb sand equal one cubic yard. A 50-lb bag contains about 0.5 cubic feet, and there are 27 cubic feet in a cubic yard (27 / 0.5 = 54). For large projects, bulk delivery is much cheaper.
What kind of sand do I use under pavers?
Use coarse concrete sand (also called masonry sand or C-33 sand) for paver bedding. Apply a 1-inch layer over compacted gravel base. Do not use play sand or beach sand — they are too fine and will wash out. Some contractors prefer polymeric sand for joints.
How deep should sand be in a sandbox?
A sandbox should have at least 6 inches of sand, ideally 8-12 inches for good play depth. For a fall zone under play equipment, you need 9-12 inches minimum per safety standards. Always use play-grade sand that is non-toxic and dust-free.
How much does sand cost?
Bulk sand: $20-$45 per ton delivered. 50-lb bags: $4-$6 each ($160-$324 per ton). Play sand is typically the most expensive type. Delivery fees range from $50-$150 depending on distance and quantity. Bulk is 3-5x cheaper than bagged for large projects.
