Question

Use the net as an aid to compute the surface area of the triangular prism.
A) 424 mm2
B) 484 mm2
C) 564 mm2
D) 624 mm2

Answer 1

Answer:

Option C. $564\ mm^{2}$

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

$SA=2(\frac{1}{2})(10)(12)+2(13)(14)+(10)(14)$

$SA=60+364+140$

$SA=564\ mm^{2}$
