How much do I need?
Work out the cubic metres then multiply it by 1.5 for loose tonnes volume or 2.4 for compacted tonnes volume.
How do I work out cubic metres?
Multiply length x width x depth. ie: 100m x 3m x 100mm is 100 x 3 x .1 = 30m3
30m3 x 1.5 = 45 tonnes of loose material
30m3 x 2.4 = 72 tonnes of fully compacted material
