Calculate installed volume
Use area times depth for uniform layers and separate zones with different depths.
Convert inches to feet before multiplying when working in cubic feet.
Use the correct sand type
Masonry, bedding, play, concrete, and fill sands can differ in gradation, moisture, and bulk density.
Do not transfer a weight conversion between products without supplier support.
Convert to bags from package data
For bagged sand, divide required volume by the package yield or use manufacturer coverage information.
Bag weight alone is not a universal volume conversion.
Account for compaction or settlement separately
A compacted base layer and a loose fill application can require different allowances.
Keep those effects separate from ordinary handling waste.
Match the supplier's sales unit
After quantity is established, convert to tons, cubic yards, or whole bags according to how the selected material is sold.
Confirm delivery minimums and current product specifications before ordering.
