Answer:

608 (D)

Explanation:

To find the area of the prism, just add all the areas in the nets together.

The rectangle in the middle has an area of 192 because it is a 12x16 triangle so you multiply the sides.

Both the rectangles on the top and bottom have an area of 160 because they are both a 10x16. The total of the 2 rectangles would be 320 because 160+160=320.

The triangles on the right each have an area of 48 because the Base=12 and the Height= 8. The formula for finding the area of a triangle is 1/2(BH). 1/2(12*8)= 1/2(96)= 48. There are 2 triangles like this so the totla area of both triangles is 96.

To find the surface area, you just add them all up. 96+320+192= 608
