How the estimate is built
cu ft = L × W × H after converting each side to feet.
Example scenario
A 4×3×2 ft box is 24 cubic feet (0.89 yd³).
FAQ
Inches only?
Select inches. 24×18×18 in ≈ 4.5 cu ft.
Why show cubic yards too?
Landscape and concrete are usually sold by the yard.
Is this shipping volume?
It’s geometric volume. Carriers often apply dim-weight rules on top.
