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

The surface area of a triangular prism is S.A.= _ +(S1 + S2 +S3) _

1 answer

The surface area of a triangular prism can be calculated using the formula:

\[ S.A. = \text{Base Area} + (S_1 + S_2 + S_3) \]

Where:

  • Base Area is the area of the triangular base,
  • \( S_1, S_2, \) and \( S_3 \) are the areas of the three rectangular lateral faces of the prism.

In summary, the completed formula is:

\[ S.A. = \text{Base Area} + (S_1 + S_2 + S_3) \]
