AI Drawing Prompt Reference

Create a model demonstrating volume calculation using a hexagon cross-section diagonal. The model features multiple surfaces and rectangles that form the upper and lower parts of the hexagon, along with front and back sections. Start by drawing the hexagon cross-section, then construct the upper and lower surfaces. Add rectangles for the front and back surfaces, and finally, calculate the volume through integration. The model should illustrate key math concepts like volume, step functions, exponentiation, arithmetic mean, scatter plots, and roots.
