\(the\ total\ surface\ area\ of\ a\ prism = sum\ of\ area\ of\ its\ sides + 2A\)
\[the\ total\ surface\ area\ of\ a\ prism = \lbrack(6 \times 5) + (6 \times 4) + (3 \times 6)\rbrack + 2(\frac{1}{2} \times 3 \times 4)\]
\[the\ total\ surface\ area\ of\ a\ prism = \lbrack 30 + 24 + 18\rbrack + 12)\]
\[the\ total\ surface\ area\ of\ a\ prism = 84{cm}^{2}\]
