Question 16
Isabelle glues 8 cubic boxes of side length 1 cm to get the letter F below. Then she paints all the surfaces of the figure except for the bottom. Find the painted area.
Grading clarification: the supplied solution interprets “the bottom” as the one square face touching the ground, and still paints the three downward-facing overhang faces. This package grades using that stated interpretation. Excluding every downward-facing face would give a different answer, explained below.
