The length of the shortest side is DC
<h3>How to determine the shortest side?</h3>
As a general rule in triangle;
The smallest angle in a triangle is opposite the shortest side.
Similarly, the largest angle in a triangle is opposite the largest side.
From the given figure of triangles, the smallest angle is angle CBD with a measure of 47 degrees.
The side opposite this angle is side length DC
Hence, the length of the shortest side is DC

Answer: 
Step-by-step explanation:
Given
The length of each cube is 
If there are 6 cubes placed over each other, then the height achieved by the cubes is
(5x^2-15x) (-2x+6)
5x (x-3) -2 (x-3)
(5x-2) (x-3)
