AI Drawing Prompt Reference

Draw an open-top rectangular prism to demonstrate dynamic volume optimization and geometric transformations. Start by constructing the base and sides of the prism, then use reflection and rotation to create the top geometric shapes. Combine all parts to form a complete open-top prism, highlighting the relationship between geometric transformations and volume changes, as well as how function graphs and unit circles can aid in understanding and optimization.
