Fill in blanks to complete the formula for the service area of the triangular prism

The surface area of the triangular prism is S.A=BLANK+(S subscript one+S subscript two+S subscript three) blank.

The formula for the service area of the triangular prism is:

S.A = 2B + (S₁ + S₂ + S₃)

B represents the area of the base of the triangular prism, and S₁, S₂, and S₃ represent the three lateral surfaces.
