Given: triangular prism bases each have an area of 6 cm² and a perimeter of 12 cm, and the altitude is 4 cm.
Find: surface area of the triangular prism .
Explanation:
[tex]\begin{gathered} surface\text{ area of the triangular prism = \lparen perimeter }\times length)+2(base\text{ area\rparen} \\ =(12\times4)+2(6) \\ =48+12 \\ =60cm^2 \end{gathered}[/tex]
Final answer: the required value of the area of triangular prism is 60 square centimeter.
