Solution:
We are required to calculate the surface area of the figure
The figure given is a regular pentagonal prism
Base length, a = 6 mi
Heght , h= 10 mi
The formula for the surface area of a pentagonal prism is
Substituting the values of a = 6, h = 10 into the formula, we have
[tex]The\text{ answer is 423.87 mi}^2\text{ \lparen 2 decimal places\rparen}[/tex]
