Slab Concrete

Slab volume in m3 with wastage.

Length(m)

Width(m)

Thickness(mm)

Wastage(%)

Concrete

2.52 m3

Volume (no wastage)2.4 m3

Formula

volume = L x W x (thickness / 1000), then add wastage

6 x 4 x (100/1000) x 1.05 = 2.52 m3

For more than about 0.5 m3, pre-mixed delivery is usually cheaper than bags.
