Answer:
A) net A
B) AB = 3 in BC = 5 in CD = 8.6 in
C) 106.6 in²
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
