The prisms and two nets shown below:<br><br> Plzzz answer part A B and C for BRILLIANT ANSWER
Arlecino [84]
Part A: Net A is correct
Net B is incorrect because de triangular sides do not close the opening left in both sides.

Part B: AB=3 in., BC=5in., CD=8.6in.

Part C: The surface area of the prism is the area of the the big rectangle in the net + the area of the 2 triangles

Area of the big rectangle
8.6• ( 3+4+5)= 103.2 in ^2
Area of the triangles
If we get the 2 trangles together along their longest side we get another rectangle
3•4 =12 in^2

Surface area of prism is 103.2+12=115.2 in^2
