The triangular prism's surface area equals the sum of its lateral surface area and twice its base area. In square units, it is measured. The formula for a triangular prism's surface area is as follows:

\begin{aligned}

&\text { Surface area }=(\text { Perimeter of the base } \times \text { Length })+(2 \times \text { Base Area })=(a \\

&+b+c) L+b h

\end{aligned}

Where, L= Length of Prism

a, b, and c = three edges of triangular bases

b = bottom edge of base triangle

h = height of base triangle

bh = total area of two triangular faces
