Answer 2

The second option, 1,008 cm²

Explanation:

This shape has 5 sides to solve for with reguards to surface area.

Let us solve for them all.

[1 & 2 - the triangles]

12 * 9 = 108 cm²

-> I am not going to divide since we have 2 congruent triangles

[3 - the bottom side]

25 * 12 = 300 cm²

[4 - the side facing away]

25 * 9 = 225 cm²

[5 - the side facing up]

25 * 15 = 375 cm²

Now we will add them together for the total.

108 + 300 + 225 + 375 = 1,008 cm²

The surface area for the triangular prism shown is 1,008 cm².
