AI Drawing Prompt Reference

Draw a rectangular prism and dynamically calculate its surface area. Start by creating three perpendicular vectors representing the length, width, and height of the prism, then use translations of these vectors to construct the vertices and edges of the prism. Next, form the faces of the prism using polygon tools and calculate the area of each face. Finally, sum the areas of all faces to obtain the total surface area, highlighting the prism's faces and vectors with different colors or styles to illustrate geometric properties and parametric modeling.
