Aprism and two nets are shown below:

part a: which is the correct net for the prism? explain your answer.

part b: write the measurements of sides ab, bc, and cd of the correct net.

part c: what is the surface area of the prism? show your work.

A) Net A is correct. The right angles are at opposite ends of the same line. Not so in Net B..

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

C) The central rectangle has length 3+4+5 = 12, and width CD = 8.6. Its area is
.. Arect = (12 in)*(8.6 in) = 103.2 in^2

The two triangles ABC form a rectangle that is 3x4, so has area
.. Atriangles = (3 in)*(4 in) = 12 in^2

The total surface area is (103.2 +12) in^2 = 115.2 in^2.
