• He pointed to one corner, in which lay the great Head, made out of many thicknesses of paper, and with a carefully painted face. tree →

Note

Thickness is a length, so it uses length units (mm, cm, m). In maths, a stack's height = number of items × thickness of each. Safety: never walk on ice unless an adult says it is thick enough.
