\qquad\qquad\huge\underline{{\sf Answer}}


\textsf{Let's calculate the surface area of given right prism}


\textbf{Area of Triangles :}


  • \sf{(1)/(2)\cdot 16\cdot 12}


  • \sf{8×12}


  • \sf96 \: \: cm {}^(2)


\textsf{Since there are two triangles, }


\textsf{Area of Triangles = 96 × 2 = 192 cm²}


\textbf{Now, calculate the Areas of rectangles :}


  • \textsf{Area - 1 = 12 × 10 = 120 cm²}


  • \textsf{Area - 2 = 16 × 10 = 160 cm²}


  • \textsf{Area - 3 = 20 × 10 = 200 cm²}


\textsf{Now add them all :}


  • \textsf{120 + 160 + 200 + 192}


  • \textsf{672 cm²}
