To find the surface are, we can add up the area of all of the sides.

Top:
4in x 9in = 36in^2

Bottom:
4in x 9in = 36in^2

Front:
5in x 9 in = 45in^2

Back:
5in x 9 in = 45in^2

Right:
4in x 5in = 20in^2

Left:
4in x 5in = 20in^2

Adding them all together:
36+36+45+45+20+20 = 202in^2

The surface area of the prism is 1. 202 in^2
