How to use CBM Calculator?
Suppose that the measurements are Length is 450 cm, width is 200 cm and the height is 600 cm of the rectangular carton.
$$\text{Length}\;=\;450\;\text{cm}\;=\;4.5\;\text{m}$$
$$\text{Width}\;=\;200\;\text{cm}\;=\;2\;\text{m}$$
$$\text{Height}\;=\;600\;\text{cm}\;=\;6\;\text{m}$$
Multiply the length, width and height to find CBM:
$$\text{CBM}\;=$$
$$\;\text{Length}\;*\;\text{Width}\;*\;\text{Height}$$
$$\text{CBM}\;=\;\text{4.5}\;*\;\text{2}\;*\;\text{6}$$
$$\text{CBM}\;=\;54\;\text{m}^3$$
