How to measure

The measurements are placed in order of length x width (or depth) and height. (LxWxH)

For a 2-dimensional object, such as a painting or a sheet of paper, the measurements are placed in the order of length and width. 

For example, if a painting measures 70 cm long and 50 cm wide, it would be written as 70 x 50 cm. (LxW)

Box measurements:

The Internal Measurements of the box are the useful size of the box. That is, the measures that you can take advantage of for storage.

The External Measurements are when the box is completely closed.
