Answer:

336, (B)

Step-by-step explanation:

To find the surface area, find the area of each square and triangle

10x12 + 2(6x8)/2 + 12x6 + 8x12

This would then be,

120 + 48 + 72 + 96

Surface area = 336, (B)

You made a mistake on step 2.

When finding the area of triangle, you have to divide by 2.

Hope this helps!
