3D Modeling with AR: Part 7

GOAL 7: Build this Toblerone again. This time, we'll do so by AUTHORING and TRANSFORMING GRAPHS of 2 FUNCTIONS.
[size=150]Triangular Prism[br]Bases are EQUILATERAL[br]Triangle Side = 3.5 cm[br]Prism height = 21 cm [/size]
EQUILATERAL TRIANGLE CROSS SECTION: Here's a hint.
This Toblerone model (built to scale) was made by authoring 2 functions. What kind of functions were used here?
