Find the surface area of
the prism.

Step-by-step explanation:

The surface area of the prism consists of four rectangles and two trapezoids. The sum of the areas of these polygons will give the total surface area of the prism:

Rectangle 1 (top base):

Rectangle 2 (bottom base):

Trapezoids 1 and 2 (lateral):

Rectangles 3 and 4 (lateral):

Thus the total surface area is equal to

Sample Response: Because vertical angles are congruent, angles 1 and 4 are congruent. Because corresponding angles are congruent, angles 4 and 8 are congruent. Because angle 4 is congruent to both 1 and 8, angle 1 is congruent to angle 8.
