Since all the sides of the triangular prism are congruent, they are all 5 cm long. Thus, the surface area of a triangular face is \[
\frac{1}{2}(5\text{ cm})(4\text{ cm})=10\text{ cm}^2.
\]The two triangular faces together have a total area of $2(10\text{ cm}^2) = \boxed{20}$ square centimeters.

I apologize for the confusion. Let's go step by step to find the surface area of the triangular prism.
First, let's identify the different faces of the prism:
1. The triangular base (ABC).
2. The top triangular face (DEF), which is congruent to the base triangle.
3. Three rectangular faces (ABED, BCDE, and CAEF) connecting the corresponding sides of the base and top triangles.
To find the surface area, we need to calculate the area of each face and then sum them.
1. The area of the base triangle (ABC) is $\frac{1}{2} \times \text{base} \times \text{height} = \frac{1}{2} \times 5 \, \text{cm} \times 4 \, \text{cm} = 10 \, \text{cm}^2$.
2. The area of the top triangular face (DEF) is also $10 \, \text{cm}^2$ since it is congruent to the base triangle.
3. The three rectangular faces have dimensions: ABED (5 cm by 4 cm), BCDE (5 cm by 4 cm), and CAEF (5 cm by 4 cm). Therefore, the area of each rectangular face is $5 \, \text{cm} \times 4 \, \text{cm} = 20 \, \text{cm}^2$. Since there are three identical rectangular faces, the total area of these faces is $3 \times 20 \, \text{cm}^2 = 60 \, \text{cm}^2$.
Finally, adding the areas of all the faces, we have $10 \, \text{cm}^2 + 10 \, \text{cm}^2 + 60 \, \text{cm}^2 = \boxed{80 \, \text{cm}^2}$ as the total surface area of the triangular prism.
