Question

find the surface area of the triangular prism.
finally, combine to find the total area.
area of both triangles: 36 cm²
area of the bottom rectangle: 36 cm²
area of the back rectangle: 36 cm²
area of the front rectangle: 54 cm²
total area: ? cm²

Explanation:

Step1: Add all areas

Add the area of both triangles, the area of the bottom rectangle, the area of the back rectangle, and the area of the front rectangle.
$$36 + 36+36 + 54$$

Step2: Calculate the sum

$$36+36 = 72$$
$$72+36 = 108$$
$$108+54 = 162$$

Answer:

\(162\)
