Answer:
Option C. [tex]564\ mm^{2}[/tex]
Step-by-step explanation:
we know that
The surface area of the triangular prism using the net is equal to the area of two triangles plus the area of three rectangles
so
[tex]SA=2(\frac{1}{2})(10)(12)+2(13)(14)+(10)(14)[/tex]
[tex]SA=60+364+140[/tex]
[tex]SA=564\ mm^{2}[/tex]
