The total surface area of a prism is the sum of the area of all of its sides.

The surface area = (2 area of base) + (perimeter of base height)

If the base is a rectangle or square you can use this formula:
SA = 2LW + 2(L+W)H = 2LW + 2HL + 2HW = 2(LW + LH + HW)

If the base is a circle, use this formula:
SA = 2πr² + 2πrh

If the base is a triangle, this formula will come in handy:
SA = bh + (\(\sf{s_1 + s_2 + s_3}\))h
where s₁, s₂, and s₃ are the three sides of the triangle.
