Painting I / The Personal Project
Practice question · Estimate

A layered oil method uses four layers, with five days of drying required between one layer and the next. How many days of drying does one canvas need in total?

Estimate on a scale from 0 days (0) to 40 days (40).

Hints
  1. Count the gaps between layers, not the layers.
  2. Three gaps at five days each.
Show the answer

15 (answers within ±2 count)

Why

15 days. Four layers have three intervals between them, and it is the intervals that consume the calendar. Two weeks of drying per canvas is the figure that decides whether a layered method fits a semester at all, and it does not shorten because the deadline is close.
