A cone holds exactly one third of a cylinder with the same base and height.
How it works
- Box: length × width × height
- Cylinder: π × diameter² ÷ 4 × height
- Cone: one third of the matching cylinder
Then: cubic yards = cu ft ÷ 27, gallons = cu ft × 7.48, liters = cu ft × 28.32.
Worked example
A box 4 ft long, 3 ft wide and 2 ft tall holds 24 cubic feet — that's 0.889 cubic yards, 179.5 gallons or about 680 liters.
