Many times it is necessary for teachers or students to determine the surface area of irregular objects (e.g., leaves) during laboratory investigations. The usual procedure involves laboriously tracing the outline of the object on graph paper, counting the number of square units on the paper, and then adding some "fudge factor" to estimate partially encircled squares.
