Step-by-step explanation:

Find the area of the 2 triangle faces and the 3 rectangle faces, then add the areas together to get the total surface area of the triangular prism.

[tex](16 \times 12 \times 1/2) \times 2 + (12 \times 10) + (16 \times 10) + (10 \times 20)[/tex]

Answer: 672 square centimeters

Step-by-step explanation:

20 X 10 = 200

16 X 10=160

160 + 120 + 192 + 200 =672
