Volume, Density and Weight Explained

Understand why volume can be calculated exactly while material weight remains an estimate.

Volume

Volume is the three-dimensional space the material must fill. Geometry determines it from accurate dimensions.

Bulk density includes spaces between particles and is not a universal property of a material name.

Particle size, grading, moisture, compaction and void space can change delivered weight.

Use a current supplier density for the exact product and confirm whether it describes loose or compacted material.
