Answer:

  • C. 152 units²

Step-by-step explanation:

Total surface area is the area of the net.

The rectangles have area:

  • 8*(5 + 6 + 5) = 128 units²

The triangles have area:

  • 2*(1/2*6*4) = 24 units²

Total area is:

  • 128 + 24 = 152 units²

Correct choice is C

Answer:

C. 152 square units

Step-by-step explanation:

I'll do the rectangles first because they are the easiest.

8(5)=40. There are 2 of those rectangles, so multiply by 2: 80.

6(8)=48. Add that to 80, you get 128.

The two triangles actually make a rectangle, so to save work, just multiply the base by the height: 6(4). You get 24.

Add them all up, and you get 152.
