The sum can be calculated by plugging in the values of $i$ from 3 to 5 into the given formula $i^2 + 8$ and adding them together. For $i = 3$, the term is $3^2 + 8 = 9 + 8 = 17$. For $i = 4$, the term is $4^2 + 8 = 16 + 8 = 24$. For $i = 5$, the term is $5^2 + 8 = 25 + 8 = 33$. Adding these terms together gives $17 + 24 + 33 = 74$.
