three forty eight squared inches
2 because there are 4 numbers of edges and 4 vertices

I'm not sure if you need to simplify
Answer: 
Step-by-step explanation:
Since, Here the smaller number = 2n - 1
Since, Numbers are consecutive.
Therefore, remaining numbers are 2n - 1 + 2 , 2n - 1 + 2 + 2
= 2n +1, 2n +3
Thus, the sum of these all numbers = 2n - 1 + 2n + 1 + 2n +3
=
( By equating the like terms)
