Answer 2

Answer:

The answer is the option C

Net A with $510$ square inches

Step-by-step explanation:

we know that

The surface area is equal to the sum of the areas of all the faces

In this problem the correct Net is the figure A

To find the surface area find the area of the $3$ rectangles plus the area of the $2$ triangles

so

Find the area of the $3$ rectangles

$A1=13*15+12*15+5*15=450\ in^{2}$

Find the area of the $2$ triangles

$A2=12*5/2+12*5/2=60\ in^{2}$

Adds the areas

$450\ in^{2}+60\ in^{2}=510\ in^{2}$
