Help meh Which figure is represented by the net shown below?

1

Step-by-step explanation:

I haven't done these in a few years but I was thinking that if you lay it out there are 3 sides being un 3D'd, plus the base. Making it 4 sides total.

None of  the other options have 4 sides, or are all triangles, making 1 your answer.

Hope this helps :)

x = 3 ± √(5+y)
