Answer 1

It should cut into

• 2 right angle traingles.
• One rectangle for base
• One rectangle for b ack.
• One rectangle for front
• i.e 3 rectangles and 2 right angles

2 ne t is accurate

Answer 2

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
