The positive root of 
Equate to 0

So, we have our function to be:

Differentiate the above function:

Using Newton's method of approximation, we have:

Plot the graph of
to get
--- see attachment for graph
From the attached graph, the first value of x is at 2.2; so:

So, we have:



The process will be repeated until the digit in the 6th decimal place remains unchanged



Hence:
Answer:
115 in²
Step-by-step explanation:
SA = Area of triangular surfaces + area of the square base
SA= 2bh + b²
SA = 2(5)(9)+5²
SA = 90+25
SA = 115
