<h3>What is the surface area of a prism?</h3>
It is the sum of the areas of all faces of the prism.
In this problem, the prism is composed by:
- Two squares of sides 13 mm.
- Four rectangles of sides 5 mm and 13 mm.
- One triangle with measures in mm of .
Hence, the areas in square millimeters are given by:
- .
- .
Adding them, the surface area of the figure is given by:
S = 338 + 260 + 112.6 = 710.6 mm².
