Answer 2

The correct net of the prism is net A and the surface area of the prism is 510 square inches

How to determine the surface area

To calculate the area of the triangular prism, we make use of the net A

Start by calculating the area of the rectangle.

The dimension of the rectangle is (5 + 12 + 13) by 15

So, the area of the rectangle is:

$Area = (5 + 12 + 13) * 15$

$Area = 450$

Next, calculate the area of the two congruent triangles of base 5 and height 12

$Area = 2 * 0.5 * (5 * 12)$

$Area = 60$

Sum both areas

$Total = 450 + 60$

$Total = 510$

Hence, the surface area of the prism is 510 square inches
