2 ne t is accurate

Answer 2

Answer:

A)  net A

B) AB = 3 in    BC = 5 in    CD = 8.6 in

C) 106.6 in²

Step-by-step explanation:

Part A:  

• net A is the correct net for the prism
  because the base of both triangles should be adjacent to the parallel sides of the same single rectangle

Part B:

From inspection of the diagram:

• AB = 3 in
• BC = 5 in
• CD = 8.6 in

Part C:

Area of a rectangle = width x length

Area of a triangle = 1/2 x base x height

Surface area = 2(4 x 8.6) + (3 x 8.6) + 2(1/2 x 4 x 3)

                     = 68.8 + 25.8 + 12

                     = 106.6 in²
