How it works
Volume = length × width × heightsurface area = 2 × (lw + lh + wh)
- length
- one edge of the box
- width
- the edge next to it
- height
- how tall the box is
Enter all three in the same unit. To read a volume in litres, note that 1 litre is 1000 cubic centimetres, so a 10 by 10 by 10 cm box holds exactly one litre.
