ft² to m³ needs thickness. A 100 ft² concrete slab at 4 in thickness is about 0,944 m³.
ft²

Volume
| Area | Thickness | Volume |
|---|---|---|
| 100 ft² | 4 in | 0.9439 m³ |
| 500 ft² | 4 in | 4.7195 m³ |
| 100 ft² | 6 in | 1.4158 m³ |
Formula
m³ = ft² × 0.09290304 × thickness inches × 0.0254. Without thickness, area cannot become volume.
