The formula for the surface area \( SA \) of a prism or a similar three-dimensional shape typically takes into account the area of the base and the areas of its vertical faces.

Given the variables:

  • \( Abase \): area of the base
  • \( Aface_1 \): area of face 1
  • \( Aface_2 \): area of face 2

The correct formula for the surface area \( SA \) is:

\[ SA = Abase + 2 \times Aface_1 + 2 \times Aface_2 \]

This formula includes:

  • The area of the base (\( Abase \))
  • Two times the area of face 1 (representing both identical faces, if they exist)
  • Two times the area of face 2 (also representing both identical faces)

So, the correct choice is:

\[ SA = Abase + 2 \times Aface_1 + 2 \times Aface_2 \]

This formula is used when calculating the surface area of a prism where the base is one of the regions and face 1 and face 2 are vertical sides of the prism.
