Answer:
Find the area of the 2 triangle faces first and then find the area of the 3 rectangle faces and add them together to get
![159cm^(2)\\](https://img.qammunity.org/2021/formulas/mathematics/high-school/lj1xfwtgjvd5bkdcqg9pineblhx1p30la7.png)
Explanation:
Step 1: Find the surface area of the 2 triangles
x2 =
![33cm^2\\](https://img.qammunity.org/2021/formulas/mathematics/high-school/vhv8f1evyy62vr34q01lcimsobihvr63ri.png)
Step 2: Find the surface area of the 3 rectangles
(6x7) x 3 =
![126cm^2](https://img.qammunity.org/2021/formulas/mathematics/high-school/2060rd38fzwd2tyktzuuwhnuuc1vxkks42.png)
Step 3: Add the 2 surface areas together
+
=
![159cm^2](https://img.qammunity.org/2021/formulas/mathematics/high-school/d8k9dmv4tvwch8e1u5cwgjuj2uvy8w4td0.png)
Therefore the surface area of the prism is
