Fill in the blanks to complete the formula for the surface area of a triangular prism. (1 point)
The surface area of a triangular prism is S.A.= ____+(S1+S2+S3) = ____
S.A.= 2bh+(S1+S2+S3) = 2bh + S1 + S2 + S3
What goes at the end of + S3 + = ___?
The formula for the surface area of a triangular prism should be:
S.A. = 2bh + (S1 + S2 + S3)
Here, the formula refers to the lateral surface area of the triangular prism = base perimeter * height + sum of the areas of the three triangular faces.
